1.
The circuit in figure, is to be scaled to an impedance level of 5kΩ and resonant frequency of 5 x 106 rad/sec. The possible combination of R, L, C is
Answer: Option
Explanation:
If L = 0.2 mH and C = 200 pF, ω0 = 5 x 106 rad/sec and if R is 5 kΩ, impedance level is 5 kΩ.
2.
In figure, the total power consumed is
Answer: Option
Explanation:
Use superposition theorem.
3.
If operator 'a' = 1 ∠120° then (1 + a) =
Answer: Option
Explanation:
Since 1 + a + a2 = 0, 1 + a = - a2.
4.
A current wave is i = 100e-60t The initial and final values of current are
Answer: Option
Explanation:
i(0) = 100 e-0 = 100, i(∞) = 100 e-∞ = 0.
5.
Assertion (A): The impedance of a series resonant circuit is minimum at resonance.
Reason (R): Resonance condition implies unity power factor condition.
Answer: Option
Explanation:
Since power factor is unity, impedance is minimum.
