Voltage Divider Calculator

Voltage divider calculator showing two series resistors, Vin and Vout labels, and a calculation display.

Electronics Tools Voltage Divider Calculator Calculate a two-resistor voltage divider. Solve for output voltage, input voltage, R1, or R2, then check divider current and resistor power before using the values in a real circuit. Voltage divider schematic Two resistors in series from input voltage to ground with output taken from the middle node. Vin R1 … Read more
