**In a series**circuit, the current through each

**of**the components is the same, and the voltage across the circuit is the sum

**of**the voltages across each component.

**In a parallel**circuit, the voltage across each

**of**the components is the same, and the total current is the sum

**of**the currents through each component.

Similarly, you may ask, what is the definition of parallel connection?

A

**parallel circuit**is a closed**circuit**in which the current divides into two or more paths before recombining to complete the**circuit**. Each load**connected**in a separate path receives the full**circuit**voltage, and the total**circuit**current is equal to the sum of the individual branch currents.How does a parallel circuit work?

A

**Parallel circuit**has certain characteristics and basic rules: A**parallel circuit**has two or more paths for current to flow through. Voltage is the same across each component of the**parallel circuit**. The sum of the currents through each path is equal to the total current that flows from the source.1

## How series and parallel circuits are different?

Components of an electrical

**circuit**or electronic**circuit**can be connected in many**different**ways. The two simplest of these are called**series and parallel**and occur frequently. Components connected in**series**are connected along a single path, so the same current flows through all of the components.2

## Are light bulbs brighter in series or parallel?

The

**bulbs**will only appear**brighter**if the available current to the system is not limited. This means more current (and thus more power) will be drawn from a battery into the**parallel**circuit than a**series**one and the**parallel**circuit will appear**brighter**(but will drain your battery faster).3

## What is the difference between series and parallel pickups?

**Pickups**wired in

**parallel**are brighter sounding and have considerably less output than an identical

**pickup**wired in

**series**. The same rules apply to pick ups wired in

**series and parallel**as a humbuckers coils wired in

**series and parallel**. Two

**pickups**wired in

**series**will have higher output and a fuller tone.

## What is a series current?

A

**series**circuit is a closed circuit in which the**current**follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths. In a**series**circuit, the**current**through each load is the same and the total voltage across the circuit is the sum of the voltages across each load.5

## Why do we use parallel circuits in our homes instead of series?

When appliances are connected in a

**parallel**arrangement, each of them can be put on and off independently. This is a feature that is essential in a house's wiring. Also, if the appliances were wired in**series**, the potential difference across each appliance**would**vary depending on the resistance of the appliance.6

## What happens to the voltage in a series?

The supply

**voltage**is shared between components in a**series circuit**. The sum of the**voltages**across components in**series**is equal to the**voltage**of the supply. The**voltages**across each of the components in**series**is in the same proportion as their resistances.7

## Why is the voltage in a parallel circuit the same?

In

**parallel circuits**, the electric potential difference across each resistor (ΔV) is the**same**. In a**parallel circuit**, the**voltage**drops across each of the branches is the**same**as the**voltage**gain in the battery. Thus, the**voltage**drop is the**same**across each of these resistors.8

## What happens when a light bulb burns out in a series circuit?

The same current flows through each part of a

**series circuit**. In the same way,**if one**of the**bulb**was unscrewed, the current flow to both the**bulbs**would be interrupted.**If**the**circuit**were a string of light**bulbs**, and**one**burned**out**, the remaining**bulbs**would also turn off.9

## What happens to the current in a series circuit when you add more bulbs?

If light

**bulbs**are connected in**series**to a voltage source, the brightness of the individual**bulbs**diminishes as**more**and**more bulbs are added**to the “chain”. The**current**decreases as the overall resistance increases. The**current**increases as**more bulbs are added**to the**circuit**and the overall resistance decreases.10

## How do current and voltage behave in a parallel circuit?

In a

**parallel circuit**, i.e. when all the resistors are in**parallel**to the voltage source, the voltage across all the branches in**parallel**is the same. If each**current**path P has different resistances, highest**current**flows through the path which has the least resistance i. e. an inverse relation.11

## What will happen when you add more bulbs in a parallel circuit?

If light

**bulbs**are connected in**parallel**to a voltage source, the brightness of the individual**bulbs**remains**more**-or-less constant as**more**and**more bulbs are added**to the “ladder”. The**current**increases as**more bulbs are added**to the**circuit**and the overall resistance decreases.12

## What are the advantages of using a parallel circuit?

Consistent voltage. Most appliances require at least 110 volts of electricity. One of the

**advantages**of**parallel circuits**is that they ensure all components in the**circuit**have the same voltage as the source. For instance, all bulbs in a string of lights have the same brightness.13

## What happens to the brightness of the bulbs in a series circuit?

If light

**bulbs**are connected in**series**to a voltage source, the**brightness**of the individual**bulbs**diminishes as more and more**bulbs**are added to the “chain”. The current decreases as the overall resistance increases. The current increases as more**bulbs**are added to the**circuit**and the overall resistance decreases.14

## Are solar panels connected in series or parallel?

If you had 4

**solar panels**in**parallel**and each was rated at 12 volts and 5 amps, the entire array would be 12 volts and 20 amps.**Series**circuits have only one path for current to travel along. When wiring**solar panels**in a**series**, the voltage is additive, but the amperage remains the same.15

## What is the definition of voltage drop?

**Voltage drop**is defined as the amount of

**voltage**loss that occurs through all or part of a circuit due to impedance. A common analogy used to explain

**voltage**, current and

**voltage drop**is a garden hose.

**Voltage**is analogous to the water pressure supplied to the hose.

## What is current measured in?

In electric circuits this charge is often carried by moving electrons in a wire. The SI unit for

**measuring**an electric**current**is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric**current**is**measured**using a device called an ammeter.17

## What will happen if you add more bulbs in a parallel circuit?

Since each light

**bulb**in a**parallel circuit**is connected to the voltage source, the voltage for each**bulb**should remain the same as**more bulbs are added**to the**circuit**. The brightness of the light**bulbs**in a**parallel circuit**will not change as**more bulbs are added**to the**circuit**.18

## What happens when a light bulb goes out in a parallel circuit?

**If**the light

**bulbs**are connected in

**parallel**, the current flowing through the light

**bulbs**combine to form the current flowing in the battery, while the voltage drop is 6.0 V across each

**bulb**and they all glow.

**One bulb**burning out in a series

**circuit breaks**the

**circuit**.

## What are 2 differences between series and parallel circuits?

In a

**series circuit**, the current through each of the components is the same, and the voltage across the**circuit**is the sum of the voltages across each component. In a**parallel circuit**, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.20

## What is the definition of a parallel circuit?

A

**parallel circuit**is a closed**circuit**in which the current divides into two or more paths before recombining to complete the**circuit**. Each load connected in a separate path receives the full**circuit**voltage, and the total**circuit**current is equal to the sum of the individual branch currents.
