Current Electricity Charging Discharging Of Capacitors Question 137
Question: In the figure shown, the capacity of the condenser C is $ 2,\mu F $ . The current in $ 2,\Omega $ resistor is
[IIT 1982]
Options:
A) 9 A
B) 0.9 A
C) $ \frac{1}{9}A $
D) $ \frac{1}{0.9}A $
Show Answer
Answer:
Correct Answer: B
Solution:
No current flows through the capacitor branch in steady state. Total current supplied by the battery i $ =\frac{6}{2.8+1.2}=\frac{3}{2} $ . Current through 2 W resistor $ =\frac{3}{2}\times \frac{3}{5}=0.9A $
