Potential difference between points P an...

Potential difference between points P and Q would be ......

A

9.6 V

B

6.6 V

C

4.8 V

D

3.2 V

Text Solution

Verified by Experts

The correct Answer is:
D
3.2V
Current in the circuit ,
I = `(epsilon)/(100 + 100 + 80 + 20)`
`I = (48)/(300) = 0.16` A
Potential difference between P and Q, V = I (R)
= 0.16 xx 20 = 3.2 V
