AIIMS 2019 Physics Capacitors MCQ Question
Find charge on the capacitor after 1 sec of opening the switch at t = ∞?
20e^-10 μC
25e^-10 μC
30e^-10 μC
35e^-10 μC
Correct Answer
Detailed Explanation
After the switch is opened at , the capacitor will discharge according to the formula , where is the initial charge, is the resistance, and is the capacitance. Given that the charge after 1 second is , this indicates that the initial charge was set to yield this value at with the specified and values. The other options (A, C, D) do not match the calculated discharge value, as they represent incorrect initial conditions or time constants.
