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.

Q1:

What type of electronic component could be used instead of one of the resistors in a potential divider to create a light-sensing circuit?

Q2:

Chloe creates the potential divider shown in the diagram. π ο§ has a value of 30 Ξ©, and π ο¨ has a value of 90 Ξ©. What ratio of output voltage to input voltage does this produce?

Q3:

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?

Q4:

A potential divider has an input voltage of 48 V. The resistance of the second resistor, π 2 , is 100 kΞ©. The output voltage is drawn across the second resistor, π 2 . What resistance must the first resistor, π 1 , have in order to produce an output voltage of 32 V?

Q5:

A potential divider has an input voltage of 36 V. The resistance of the first resistor, π 1 , is 48 Ξ©. The output voltage is drawn across the second resistor, π 2 . What resistance must the second resistor have in order to produce an output voltage of 18 V?

Q6:
