Electric Potential Difference

The Electric Potential Difference calculator compute the change in voltage based on the change of energy and the charge.

INSTRUCTIONS: Choose units and enter the following:

• (Ue) Energy
• (q) Charge

Electric Potential Difference (ΔV): The difference is returned in volts.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The change in electric potential is defined as the potential energy per unit charge.

ΔV =  U_{e /}  q

Where:

• ΔV = Electric Potential Difference
• U_e is the energy storage
• q is the electrical charge
