Ohm's law calculator

Calculates power, resistance, voltage or current from two known values

Example 1: Must calculate the current of a circuit consuming 50 watts with a 12 volt supplyView example
Example 2: Must calculate the resistance to have 100 microvolt output with 20 milliamp currentView example
You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga

Fill at least two known values of the fields
  • Voltage - Voltage of the circuit
  • Current - Current of the circuit
  • Resistance - Resistance of the circuit
  • Power - Power of the circuit
