Magnitude of current at resonance in R-L-C circuit________?
Correct answer: A. depends upon the magnitude of R
- A. depends upon the magnitude of R
- B. depends upon the magnitude of L
- C. depends upon the magnitude of C
- D. depends upon the magnitude of R, Land C
Explanation
At series resonance, inductive and capacitive reactances cancel, leaving impedance equal to R. Thus the resonance current, I = V/R, depends on the resistance for a fixed supply voltage.
