Four capacitors of capacitance 10 µF and a battery of 2V are arranged as shown. How much µC charge will flow through AB after the switch S is closed?
Text Solution
Verified by ExpertsThe correct answer is:
45
(45)
Sol. When switch is open = C eq. = 
µ F
q i = C eq. V = 
× 2 = 15 µC
When switch is closed
C eq. = 30 µF
q f = 30 × 2 = 60 µC
Charge flow through AB = q f – q i = 45µC
