Joules to Volts Calculator

Find voltage from energy and charge.

Voltage (V) 6

Formula: V = energy ÷ charge

Step-by-step with your numbers:

1. Values used:

2. Energy = 12 J

3. Charge = 2 C

5. Voltage = Energy / Charge = 12 / 2 = 6V

Did we solve your problem today?

Voltage is energy per unit charge.

The math behind it

V = joules ÷ coulombs. One volt = one joule per coulomb.

12 J over 2 C → 6 V.

Reverse?

energy = voltage × charge.
