what is the quality factor of resistance?
Correct answer: A. Zero
- A. Zero
- B. ∞
- C. Infinite
- D. Maximum but finite
Explanation
The quality factor, or Q factor, is a measure of how underdamped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its center frequency. In a purely resistive circuit, there is no energy storage element (such as an inductor or capacitor) to create oscillations. Therefore, the quality factor is zero. Options B and C suggest infinite quality factors, which are incorrect as they would require an ideal LC circuit with no resistance. Option D suggests a finite but maximum quality factor, which would imply some energy storage capability, also not applicable to a purely resistive circuit.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
