In a loss-free R-L-C circuit the transient current is__________?
Correct answer: C. sinusoidal
- A. oscillating
- B. square wave
- C. sinusoidal
- D. non-oscillating
Explanation
With no resistance, an RLC circuit has no damping, so energy transfers repeatedly between the inductor and capacitor. The resulting natural current is sinusoidal and oscillatory.
