Voltage Divider Calculator

https://circuitdigest.com

A potential divider circuit is a very common circuit used in electronics where an input voltage has to be converted to another voltage less than it. This circuit is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of Resistors.
