Electrical Engineering Questions and Answers


56)

At series resonance, the inductive reactance and capacitive reactance are never equal


Answer: Option B

Explanation:

At resonance condition XL=XC.

57)

A lower Q produces a narrower bandwidth.


Answer: Option B

Explanation:

Q factor = fr/BW.

So for low Q BW is not narrower it should be wider.

58)

Answer: Option B

Explanation:

That's parallel RLC circuit called as a Tank circuit.

59)
