Q21 / 142 · NTA Abhyas (JEE Main) 2020 · Physics · Electrostatics
In the given circuit, initially switch is closed and and are open. After charging of the capacitor, at , is open and and are closed. If the relation between inductance, capacitance and resistance is , then find the time (in ) after which the current passing through the capacitor and inductor will be the same. [given , ]


Correct answer: 1
Solution
Charge on capacitor after complete charging
Now at two circuits are formed,
(B) Growth of current in circuit
now
given
Now at two circuits are formed,
(A) Discharging of capacitor
(B) Growth of current in circuit
now
given
Hence, the correct answer is 1.
