Current Electricity Charging Discharging Of Capacitors Question 726
Question: The circuit shown here has two batteries of 8.0 V and 16.0 V and three resistors $ 3\Omega $ , $ 9\Omega , $ and $ 9\Omega , $ a capacitor of $ 5.0\mu F. $ How much is the current I in the circuit in steady state?
Options:
A) 1.6 A
B) 0.67 A
C) 2.5 A
D) 0.25 A
Show Answer
Answer:
Correct Answer: B
Solution:
[b] In steady state capacitor is fully charged hence no current will flow through line 2. By simplifying the circuit Hence resultant potential difference across resistances will be 8.0 V. This current $ \text{or, }I=\frac{2}{3}=0.67A $
