# What is the difference between a series and a parallel circuit?

**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.

### What is the series circuit?

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.#### What are the rules for current and voltage in a series circuit?

The same current flows through each part of a**series circuit**. The total resistance of a**series circuit**is equal to the sum of individual resistances.**Voltage**applied to a**series circuit**is equal to the sum of the individual**voltage**drops.#### How many paths are there in a series circuit?

The defining characteristic of a series circuit is that there is only**one path**for electrons to flow.#### What does it mean to be a closed circuit?

**closed circuit**. An electric**circuit**through which current can flow in an uninterrupted path. Compare open**circuit**. A television system in which the signal is usually sent by cable to a limited number of receivers.

### What is Series circuit connection?

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.#### 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**.#### How series and parallel circuits are different?

**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.

### How does a series of circuits work?

In a

**series circuit**, the current is the same at each resistor. If the light bulbs are identical, then the resistance is the same for each resistor. The voltage drop (I. The voltage boost in the battery will be equal to the sum of the voltage drops across all three resistors.#### Is the current in a parallel circuit the same everywhere?

In**parallel circuits**the**current**splits up so each branch has a different effective resistance (in each of the separate branches one can use the series rule again). Due to this, the**current**isn't the**same everywhere in a parallel circuit**. Most basic concepts that must be understood here are "Voltage" and "**Current**" .#### What happens if you add more light bulbs to 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.#### 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**.
