Quality factor: Potential drop across capacitor or inductor = Potential drop across R

1. IoωL / IoR
2. IoωL / IoR
3. Potential drop across capacitor or inductor = Potential drop across R
4. Quality factor

Correct answer: IoωL / IoR

Solution

The quality factor (Q) is defined as the ratio of the potential drop across the inductor or capacitor to the potential drop across the resistor in an LCR circuit. This is given by IoωL / IoR.
