1. increases with Q increasing frequency
2. varies linearly with frequency
3. increase with increasing frequency because R increases at high frequency
4. decrease after the peak frequency because R increases at H.F. the correct statements are

Assertion (A): In many materials, dielectric polarization causes mechanical distortion.

Reason (R): If dielectric polarization causes mechanical distortion then mechanical distortion must cause dielectric polarization.

1. The circuitry of ripple counter is more complex than that of synchronous counter.
2. The maximum frequency of operation of ripple counter depends on the modulus of the counter.
3. The maximum frequency of operation of synchronous counter does not depend on the modulus of the counter.

1. Full adder
2. Full subtractor
3. Half adder
4. J-K flip-flop
5. Counter

Assertion (A): If the duty cycle of chopper is low the current would not become discontinuous

Reason (R): If the time constant L/R of the load in chopper is low the current may become discontinuous.
