# Whats the difference between TERMINAL P.D. and normal P.D.? watch

1. Can someone please explain the potential difference... KEK. jk
Whats the difference between P.D. and terminal P.D.
2. bump
3. Potential difference is defined as the difference in electrical potential between two points.
As V=E/Q, it is the work done per coulomb of charge. There is a potential difference across a component in a circuit as some work is done as it passes through it.

Terminal potential difference is the difference in electrical potential across the terminals of a battery.
In a battery, chemical reactions occur to provide energy for current to flow from the negative to the positive terminals. So this chemical energy is transferred to each unit of charge as electrical energy. This electrical energy supplied by the battery is the electromotive force. As it the coulombs of charge pass through the battery work is done to the battery's internal resistance. This causes a potential drop.
Terminal pd= electromotive force minus potential difference across the internal resistance.

lol i hope my explanation is okay. my knowledge of electricity is a bit dodgy.
Terminal pd is I guess a form of pd, instead of between two points in say a circuit, it is the difference in potential across the postive & negative terminals of a battery.
