An inductor (L =0.03 H) and a resistor `(R = 0.15k(Omega))` are connected in series to a battery of 15 V EMF in a circuit shown below. The key `K_(1)` is opened and Key `K_(2)` is closed simultaneously. At t =1 ms, the current in the circuit will be `(e^(5) = 150)`

An inductor (L =0.03 H) and a resistor (R = 0.15kOmega) are connected in series to a battery of 15 V EMF in a circuit shown below. The key K_1 has been kept closed for a long time. Then at t=0 The key K_(1) is opened and Key K_(2) is closed simultaneously. At t =1 ms, the current in the circuit will be (e^(5) = 150)

An inductor (L = 0.03 H) and a resistor (R = 0.15 kOmega ) are connected in series to a battery of 15 V EMF in a circuit shown below The key K_1 has been kept closed for a long time.
