Answer 1

Answer:

Explanation:

Current in a. c circuit = V / total impedance

impedance = $\sqrt{(R^2+( \omega L-\frac{1}{\omega C})^2 }$

In resonance maximum current flows and for maximum current  impedance should be minimum .

For it  $\omega L$ = $\frac{1}{\omega C}$

ω² = $\frac{1}{LC}$

OPTION  b is correct.

At resonance power is maximum because current is maximum and impedance is minimum.

OPTION c is correct.

quality factor = $\frac{1}{R}\sqrt{\frac{L}{C} } }$

Option  f is correct.
