Ohm’s Law Calculator provides the direct method to perform Electrical Calculations by one thumb click. Enter any two quantities from Voltage, Current, Power, Resistance and other two values will be provided to you.

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
