Select a relationship to calculate the unknown value using Ohm's law and power identities.

Voltage(Volts (V))

Current(Amperes (A))

Multiply voltage by current to find electrical power in watts.

Enter values to solve

Voltage (V) = Current (A) × Resistance (Ω). Knowing two values lets you calculate the third.

Currents stay the same, voltages add up, and total resistance is the sum of each resistor.

Voltages stay equal, currents split, and total resistance drops with each additional branch.
