In the circuit shown, the steady state is reached with S open S is closed at t = 0, the current I in the 1 Ω resistor connected is to be determined at t = 0+ is given by
Answer: Option
Explanation:
If steady is reached L will be short circuited the current in 1 Ω resistor I = 4/2 
2A.
It will act as current source in parallel with inductor.
Now apply superposition theorem consider 4 volt source, current source will be open and inductor also open.
Current in R' = 1 Ω resistor = 2A.
When current source consider, voltage source will be short circuited and current due to inductor is 1A in opposite direction.
Total current 2 - 1 = 1 A.

The value of the inductance of coil in which a current increases linearly from zero to 0.1A in 0.2 second producing a voltage of 5 volts is __________ .
Answer: Option
Explanation:
10 = L L = 10 H.
38.
An RLC series circuit is excited by an ac voltage v = 1 sint. If L = 10 H, C = 0.1 F peak value of voltage across R is
Answer: Option
Explanation:
It is a series resonant circuit and peak voltage across R is equal to peak value of source voltage.
