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 π‘‰οŠ§.

Find the voltage π‘‰οŠ¨.

Find the resistance 𝑅οŠͺ.

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 π‘…οŠ§.

Find the potential difference across π‘…οŠ¨.

Find the potential difference across π‘…οŠ©.

Find the potential difference across 𝑅οŠͺ.

Find the potential difference across π‘…οŠ«.

Q3:

Consider the circuit shown in the accompanying diagram.

What is the terminal voltage of the battery?

What is the potential drop across resistor π‘…οŠ¨?

Q4:

The circuit shown in the diagram is known as a voltage divider. The symbol consisting of three horizontal lines represents β€œground” 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 𝑅=2.00kΞ©, 𝑅=3.00kΞ©, 𝑅=1.00kΞ©, and 𝑉=210inV.

What is the output voltage 𝑉out of circuit (a)?

What is the output voltage 𝑉out of circuit (b)?
