From the attached image, the answers are 2,3,6,7
Explanation:
Maximum power occurs at resonance, i.e. , not when impedance is greater than resistance
Resonance occurs when the Inductive reactance equals the capacitive reactance, i.e. , not
and when,
Therefore, option B is correct
Since the formula for impedance is , at resonance, Z = R i.e. the impedance is minimum
At resonance, there is maximum power and minimum impedance
Thew Quality Factor,
The impedance Z is always larger than the resistance R, note that it is not stated that this condition is at Resonance, that makes it correct.
