Potential difference, work done and charge are related by this equation:

**V = W / Q**

V=PD in volts, V

W=work done in joules, J

Q=charge in coulombs, C

**V = E / Q**

E=energy transferred in joules, J

The **resistance of a component** is calculated using the equation:

**R = V / I**

R=resistance in ohms

V=PD in volts, V

I=current in amps, A
