Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R): 
Assertion (A): When ac circuit contains resistor only, its power is minimum.
Reason (R): Power of a circuit is independent of phase angle.
In the light of the above statements choose the correct answer from the options given below:
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True but (R) is False.

If R and L are resistance and inductance of a choke coil and f is the frequency of current through it, then the average power of the choke coil is proportional to:
1.  \(R ~\)
2.  \(\frac{1}{f^2}\)
3.  \(\frac{1}{L^2}\)
4.  All of these
