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 supply | View example |
| Example 2: Must calculate the resistance to have 100 microvolt output with 20 milliamp current | View 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
