# Worksheet: Potential Difference between Points in a Circuit

In this worksheet, we will practice calculating the potential difference across components in multicomponent electric circuits by using Kirchhoff's voltage law.

Q1:

Consider the circuit shown.

Find the voltage .

Find the voltage .

Find the resistance .

Q2:

The circuit shown in the accompanying diagram contains resistors connected in series, each of which has a potential difference across it.

Find the potential difference across .

Find the potential difference across .

Find the potential difference across .

Find the potential difference across .

Find the potential difference across .

Q3:

Consider the circuit shown in the accompanying diagram.

What is the terminal voltage of the battery?

What is the potential drop across resistor ?

Q4:

The circuit shown in the diagram is known as a voltage divider. The symbol consisting of three horizontal lines represents βgroundβ and can be defined as the point where the potential is zero. The voltage divider is widely used in circuits and a single voltage source can be used to provide reduced voltage to a load resistor as shown in the second part of the figure where , , , and .
