Consider the circuit shown in the given figure. What will be the charge on the capacitor in the steady state?
Options
- A
- B
- C
- D
Correct answer
B.
Step-by-step solution
In the steady state, the capacitor acts as an open circuit. Thus, no current flows through the middle branch containing the capacitor and the resistor.
The steady current flows only through the and resistors.
The equivalent resistance of the circuit is:
The current in the circuit is:
The potential difference across the resistor is:
Since the capacitor branch is in parallel with the resistor, the potential difference across the capacitor branch is also . As there is no current in this branch, the voltage drop across the resistor is zero.
Therefore, the potential difference across the capacitor is .
The charge on the capacitor is:
