Joules to Volts Calculator
Find voltage magnitude from electrical energy transferred and positive charge magnitude.
Formula
V = E/Q.
Transferred energy: 24 J · Charge magnitude: 2 C · Voltage magnitude ≈ (24 J)÷(2 C)
How to use
- Enter electrical energy.
- Enter the corresponding positive charge.
- Read voltage in volts.
Examples
- 24 J per 2 C gives 12 V.
Frequently asked questions
Can joules alone give volts?
No. Voltage is energy per charge.
Is this capacitor voltage?
No. Stored capacitor energy follows E = ½CV².
What signs are supported?
This tool uses nonnegative energy and positive charge magnitudes.
