Weaam:
What is meant by an electromotive force of 12V
O/N 08 Q8 part C second varient.
thaaaaank yoou!
Ghost Of Highbury:
okay, im off guyz. 1:30 am ! ::)
Good luck to y'all !! Hope you do well!
Sorry if its early to leave , but i have to go, 1:30 am here!!
@weaam = Attached. Green - Air, Black = Dust. Imagine all those collisions taking place. They simply cant fall down

The electromotive force of any battery is the amount of energy in joules provided to each coloumb (C) of charge, as it passes through the circuit.
So, the electromotive force of 12 V would mean,
the battery provides 12 J of energy to each coloumb (C) of charge as it passes through the circuit.

A cell (or battery) pushes electrons round a circuit.
It is a kind of electron pump.Different cells can exert different electrical pressures.
This electrical pressure is called electromotive force or e.m.f and it is measured in volts(V).

hope u understand
