Question: Potential difference across C<sub>1</sub> and C<sub>2</sub>, when V<sub>A</sub> – V<sub>B</sub> = 5V...

Potential difference across C1 and C2, when VA – VB = 5V are

A

V and 10 V

B

15 V and 15 V

C

10 V and 5 V

D

7.5 V and 7.5 V

Answer

10 V and 5 V

Explanation

Solution

By KVL between A & B

VA –+ 10 –= VB

(VA – V­B) + 10 = 3/2 Q × 10–1 ̃ Q = 10 mC

\ V1 mc = Q/C = 10mC/1mF = 10 V, V2mC­ = Q/C

= 10mC/2mF = 5V
