The work done in moving a charge "Q" coulomb against a potential deifference of "V" volts is QV
Explanation:
When any particle contains a charge ”Q” coulomb is moved against the potential of “V” volts, work needs to be done on the charge by an externally aided force. This work done increases the PE (Potential energy) of the charge which equals the difference in the PE of the body.
As a consequence of the change in PE of the two points (initial and final), the potential difference is generated. Hence this difference can be detailed as-
ΔV=Work/Charge
Hence work done= Charge*Potential difference
Work done= QV
