Calculating Voltage (V)

Voltage, also known as electric potential difference, is the force that pushes electric charges through a conductor. This calculator helps you find the voltage when you know the current and resistance.

The Formula

$V = I \times R$

Where:

V: Voltage (Volts, V)
I: Current (Amperes, A)
R: Resistance (Ohms, Ω)

Example

If a circuit has a current of 2 Amps flowing through a resistor of 5 Ohms, the voltage across the resistor is: $V = 2 \text{ A} \times 5 \text{ } \Omega = 10 \text{ V}$
