# Ohm’s Law Calculator

Ohm’s law calculator is used to calculate any two of voltage, current, power, and resistance from other two parameters.

Example: Find the amount of current passing through 10k Resistor, when a 10VDC battery is connected as input?

Solution: I = V/R = 10 V / 10 k = 1 mA.

Example: Find the value of unknown resistance, if a 10VDC source connects and a current of 50 mA flows through the resistor.

Solution: R = V/I = 10 V / 50 mA = 200 ohm
