Determine potential drop between the terminals of a battery, Electrical Engineering

Assignment Help:

The potential drop between the terminals of a battery is equal to the battery's EMF when:

a) No current is drawn from the battery

b) A very large current is drawn from the battery

c) The internal resistance of the battery is very large

d) The resistance in the external circuit is small

And:

The potential drop between the terminals of a battery is equal to the battery's EMF when no current is drawn from the battery.
