Electrostatic Potential And Capacitance

Question

Define 'quality factor' of resonance in a series LCR circuit. What is its SI unit?

Solution

Quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation.
Quality factor is expressed as,
$straight Q space equals space fraction numerator straight omega subscript straight o straight L over denominator straight R end fraction$
Q-factor is a dimensionless quantity.
