Potential Divider Calculator is an online tool for electrical and electronic circuits to measure Voltage Output. In electrical and electronic circuits, the potential divider used to control the output voltage with respect to the resistors R_a and R_b. Where the input voltage is referenced to the ground. When it comes to online calculation, this Potential Divider Calculator can assist you to find out the output voltage value based on the values of input voltage, resistors R_a and R_b. The potential divider output voltage can be mathematically derived from the following formula
