Detailed Solution

Assertion is true but the reason is false.
Assertion:
When a battery is short-circuited then the external resistance becomes zero and therefore the terminal voltage is also zero. Inside a battery, there is an internal resistance and therefore the current is non-zero.
Reason:
The current will only flow in one direction (positive or negative) and not at all potentials in a short circuit.
