# Why is the voltage in a series circuit different?

## Why is the voltage in a series circuit different?

The total voltage in a series circuit is equal to the sum of all the individual voltage drops in the circuit. As current passes through each resistor in a series circuit, it establishes a difference in potential across each individual resistance.

## What is the purpose of voltage in an electrical circuit?

Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

How is voltage different in series and parallel circuits?

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.

### How is voltage through a circuit calculated?

Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor. If the circuit is broken at any point, no current will flow.

### Why does voltage add up in a series circuit?

When you add two batteries in series the potentials (voltage) are added because since the same charge is moved twice each time thru the same voltage (potential) the total work done is 2 * V but the current flow remains the same.

How does voltage change in a circuit?

When current flows through a voltage source it experiences a voltage increase. When current flows through a resistor it experiences a voltage drop. When current flows around a circuit it experiences no change in voltage.

## Why do the voltages across components in a series circuit add up to the voltage across the battery?

if two identical components are connected in series, the supply voltage divides equally across them. if one component has twice as much resistance as the other, the voltage across the higher resistance component is double the voltage across the lower resistance component.

## What happens to the voltage in a parallel circuit?

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. If one of the parallel paths is broken, current will continue to flow in all the other paths.
