# 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 “ground” 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 .
