For the wave shown in figure, the average value is
Answer: Option
Explanation:
Average value = 10 + 0.5 x 10 = 15 A.

The dc voltage applied to an R-L series circuit is suddenly changed from V1 to V2. The expression for transient current is
either (a) or (c)
Answer: Option
Explanation:
The final steady state current is 
and transient term must depend on both V1 and V2.
48.
One ampere means the flow of
Answer: Option
Explanation:
As per definition one ampere means 1 coulomb per second.
49.
For the following circuit a source of V1(t) = e-2t is applied, then the resulting response V2(t) is given by
e-2t + e-t
e-t
e-t - e-2t
Answer: Option
Explanation:
.
50.
When R and C are connected in parallel, phase angle of Y is positive.
Answer: Option
Explanation:
I = YV. Since I leads V, phase angle of Y must be positive.
