Ohms law calculator with power (DC)
The ohms law calculator calculates voltage, current, resistance and power according to ohms law for DC.
Ohms law calculator parameters
- Voltage (V): DC voltage in Volts (V).
- Current (I): DC current in ampere (A).
- Resistance (R): Resistance in ohm (Ω)
- Power (P): Power in Watts (W)
How to calculate voltage, current and resistance with ohms law?
Ohms law formula for current is
Ohms law formula for voltage is
\(V=\displaystyle I \cdot R\)
Ohms law formula for resistance is
Formula for DC power
\(P=\displaystyle V \cdot I\)
