Question

5. In the given circuit, two cells of different internal
resistance 6 2 and 2 but same emf are
connected in series with external resistance R If
potential difference across cell of internal
resistance 6 Q is zero then R is


ans is 4ohm can anybody explain it ​

Answer 1

Answer:

Explanation:

take out the current .

i= 2E/8+R

now E = i x 6 as the potential is 0 in it.

so you will get R as 4 ohms.
