What is the potential difference between points A and B in the following circuit?

A

10 V

B

5 V

C

2.5 V

D

20 V

Text Solution

Verified by Experts

The correct Answer is:
B
Equivalent resistance of the circuit `= (5 + 5) || (5 + 5) =5Omega`
Total circuit current = 10/5 = 2 A
Current in each branch is 1A
So, potential difference between points A and B i.e. across the `5Omega` resistor is `1 xx 5 = 5 V`.
