Answer: Option
Explanation:

.


42.
The dual of network in figure is
Answer: Option
Explanation:

L in series gives C in parallel of the same value and vice versa.


43.
With Is disconnected I = - 1, when Is = b is connected, the value of I will become
2 A
-1 A
1 A
3 A
Answer: Option
Explanation:

I = -1 when Vs connected, when Is is open let find current in 2Ω resistor when V is shorted and I is connected.

then

I = -1 + 2 1 A.


44.
In a resistor the current is i and the voltage is v. The rate of dissipation of heat at any time t is
vi
vit
vt
vit2
Answer: Option
Explanation:

Rate of heat = rate of energy = power = vi.


45.
