The time constant of the circuit shown is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
⇒ E = 
= 
⇒ E = 2ε , r eq = 
= 0
Equivalent battery
i max = 
for Q max
⇒ 
i = 
i 2 = 
,
i 1 = 
,
i 3 = i 4 = 
potential on C = potential on 2R resistance = i 3 × 2R = ε
charge on capacitor, Q max = CV = Cε
τ =
