Lesson: Using Potential DividersPhysics
In this lesson, we will learn how to find the output voltage of a potential divider and describe how potential dividers can be used in sensing circuits.

What type of electronic component could be used instead of one of the resistors in a potential divider to create a light-sensing circuit?
Chloe creates the potential divider shown in the diagram. has a value of 30 Ω, and has a value of 90 Ω. What ratio of output voltage to input voltage does this produce?
Isabella has a light bulb that requires a 12 V potential difference across it in order to work. She only has an 18 V battery to power it. Which of the following pairs of resistors can be used to create a potential divider to power the light bulb?
