How is the Q of an RLC parallel resonant circuit calculated?
The correct answer is C: Resistance divided by the reactance of either the inductance or capacitance. How is the Q of an RLC parallel resonant circuit calculated is resistance divided by the reactance of either the inductance or capacitance. Q = R/X for parallel circuits. For amateur radio operators, this is important for circuit calculations. Understanding this helps when calculating Q.
Exam Tip
Parallel RLC Q = resistance divided by reactance of either L or C. Think 'P'arallel 'Q' = 'R'/'X'. Q = R/X for parallel circuits. Not X/R, not X×R, not XL×XC - just R/X.
Memory Aid
"Parallel RLC Q = resistance divided by reactance of either L or C. Think 'P'arallel 'Q' = 'R'/'X'. Q = R/X for parallel circuits. Important for circuit calculations."
Real-World Application
The Q of an RLC parallel resonant circuit: It's calculated as resistance divided by the reactance of either the inductance or capacitance. Q = R/X, where X is XL or XC (they're equal at resonance). This is the calculation - R/X for parallel circuits.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Reactance divided by resistance isn't correct - for parallel circuits, Q = R/X. Reactance/resistance is wrong.
Option B: Incorrect. Reactance multiplied by resistance isn't correct - for parallel circuits, Q = R/X. Reactance×resistance is wrong.
Option D: Incorrect. Reactance of inductance multiplied by reactance of capacitance isn't correct - for parallel circuits, Q = R/X. XL×XC is wrong.
