Is it possible that any battery has some constant valur of emf, but the potential difference between the plates is zero?

A

Not possible

B

Yes, if another identical is joined in series

C

Yes, if another identical battery is joined in opposition

D

Yes, possible, if another similar battery is joined in parallel

Text Solution

Verified by Experts

The correct Answer is:
C

If an identical battery is connected in opposition, net emf = E - E = 0 and the current through circuit will be zero, although each one of them has constant emf.
