What happens to the voltage across the inductor when the Q factor decr...
We know that voltage across the inductor in resonance condition is equal to Q times the source voltage. Hence as the Q factor decreases, the voltage across the inductor also decreases.

Effect of Decreasing Q factor on Voltage Across the Inductor:
Increasing Q factor means that the inductor has less resistance and losses, resulting in a higher quality factor. Conversely, when the Q factor decreases, the voltage across the inductor will decrease.
Reasoning:
- The Q factor of an inductor is defined as the ratio of reactance to resistance.
- A higher Q factor implies that the reactance is much larger compared to the resistance, resulting in a higher voltage across the inductor.
- Conversely, when the Q factor decreases, it means that the resistance has become more significant relative to the reactance.
- As a result, the voltage drop across the inductor decreases because more of the applied voltage is being dropped across the resistance.
Therefore, the correct answer is option 'b) Decreases'. When the Q factor decreases, the voltage across the inductor decreases due to the increased significance of resistance compared to reactance in the circuit.
