16.
A wave trap is a
Answer: Option
Explanation:
It has R and L in one branch and a variable capacitance in second branch.
17.
In following circuit, steady state is reached with S open, S is closed at t = 0, the current I at t = 0+ is given by
Answer: Option
Explanation:
When steady state is reached with s open, capacitor will act as open circuit
Current in 4Ω resistor will be = 6A at steady state.
Voltage across 4Ω = 6 x 4 
24 volt.
Current in 2Ω resistor due to 6A 3A current due to 16 V, source.
I = 16/2 8A, this current divide in (2 + 2) Ω is 4Ω resistor current in 2Ω resistor 4A + 3A 7A.
18.
In an ac series RLC circuit the maximum phase difference between any two voltages can be
Answer: Option
Explanation:
Voltage across inductance leads the current by 90° and voltage across capacitance lags the current by 90°.
19.
