16.
In a purely capacitive circuit, the current __________ the voltage by __________ .
Answer: Option
Explanation:
In inductive circuit current leads the voltage by 90°.
17.
A circuit has two branches in parallel and each branch has only one element. The applied voltage and source current are v = 200 sin (200t + 30°) and i = 50 sin (200t + 50°). If one branch has capacitor, the other branch contains
Answer: Option
Explanation:
The current is leading the voltage. Therefore, it is an RC circuit.
18.
In the circuit shown in figure, Is = 4A, Vs = 4, the voltage V is given by
Answer: Option
Explanation:
Using superposition theorem, when Is = 0, v1 = 2 volt, when Vs = 0, current is 2A in 2Ω,
so voltage 
2 x 2 = 4 volt.
Net 2 + 4 = 6 volt.
19.
The average value of wave in figure is
Answer: Option
Explanation:
20.
