Two ideal batteries having emf E1 and E2...

Two ideal batteries having emf `E_1 and E_2` are connected as shown in Figure .The values of resistances are chosen in such a way that ammeter reading is zero. The reading of voltmeter will be (consider the meters to be ideal)

A

`E_1`

B

`E_2`

C

In between `E_1 and E_2`

D

nothing can be predicted about voltmeter reading from the given information.

Text Solution

Verified by Experts

The correct Answer is:
B
b. The ammeter is not showing any reading. It means the potential
drop across CB due to `E_1` is equal to that of the emf `E_2` . And this is the reading of the voltmeter.
