Q. An inductor of inductance
2.0H and a resistor of resistance
10Ω are connected in series to a battery of
EMF20V in a circuit as shown. The key
K1 has been kept closed for a long time. Then at
I=0,K1 is opened and key
K2 is closed simultaneously. The rate of decrease of current in the circuit at
t=1.0s will be
