# What are the rules for series and parallel circuits?

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.A.

### How does voltage work in a series 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 voltage in a circuit?

Defined in these scientific terms, 1 volt is equal to 1 joule of**electric**potential energy per (divided by) 1 coulomb of charge. Thus, a 9 volt battery releases 9 joules of energy for every coulomb of electrons moved through a**circuit**.#### What are the rules for resistance in a series circuit?

Resistor in**series**. When resistors are connected in**series**, the current through each resistor is the same. In other words, the current is the same at all points in a**series circuit**. The total**resistance**of a number of resistors in**series**is equal to the sum of all the individual resistances.#### 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 are the rules for resistance in a series circuit?

Resistor in

**series**. When resistors are connected in**series**, the current through each resistor is the same. In other words, the current is the same at all points in a**series circuit**. The total**resistance**of a number of resistors in**series**is equal to the sum of all the individual resistances.#### What is the definition of a 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 is the potential difference in a series circuit?

Two identical resistors connected in**series**will share the**potential difference**. They will get half each. For example if two identical resistors are connected in**series**to a 3 V cell then the**potential difference**across each of them is 1.5 V.#### What is the Ohm's law?

The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.**Ohm's Law**is given by: V = I R where V is the potential difference between two points which include a resistance R.
