Electric Voltage Calculator

The electrical voltage is defined as the potential difference between two points. Mathematically voltage is defined as the ratio of energy to charge.

Basic Formula For Voltage

Voltage Formula: V = W/Q

Where

V = Voltage in volts

W = Energy in Joules

Q = Charge in coulombs

Voltage Calculation Example

Problem Statement: 50 J of energy is required to move a charge of 5 C from one point to the other. What is the voltage between points?

Solution: V = W/Q

V = 50 J/5C = 10 volts
