Answer: Option
Explanation:
For class C insulators temperature limit is 180°C.
9.
Assertion (A): Superposition theorem can be used to find the output of a full wave rectifier excited by sinusoidal signal sources of different frequencies connected in series.
Reason (R): Superposition theorem is valid for all linear systems.
Answer: Option
Explanation:
Sinusoidal sources of different frequencies cannot be used for a rectifier circuit.
10.
The current through a 1 mH inductance is i(t) = 2.56 x 10-2 - 4 x 103 t for 2 ≤ t ≤ 20 μ sec. The voltage across the inductor is
Answer: Option
Explanation:
1 x 10-3 
(2.56 x 10-2 - 4 x 103t)
= 1 x 10-3 x 4 x 103
