## Question:

Amy needs 5.0 V for some integrated circuit experiments. She uses a 7.0 V battery and two resistors to make a voltage divider. One resistor is 360 {eq}\Omega {/eq}. She decides to make the other resistor smaller. What value should it have?

## Voltage Divider

A voltage divider is an electronic circuit that reduced high voltage into a lower voltage. It is composed of a series resistor and an input voltage. Here, we are investigating Amy's integrated circuit.

Given:

{eq}V_{in} = 7 \text{V}\\ V_{out} = 5 \text{V}\\ R_2 = 360 \Omega\\ R_1 = ? {/eq}

The second resistor Amy needed to output 5 V can be...

Electrons are motivated to power circuits through voltage sources, which can be clearly seen in batteries and other everyday items. Generators can come in the form of nuclear, coal, natural gas, hydroelectric, and wind power to generate voltage. In this lesson, learn about energy conversion, voltage, voltage sources, and examples of these things in everyday life, including batteries and generators.
