PhysicsInteger+4 / -1Question 23 of 90

A sinusoidal voltage V(t) = 200 sin2000 t volt is applied to a series LCR circuit in which L = 10 mH, C = 25 μF and R = 100 Ω. The impedance of the circuit is _______ Ω

Your answer

Answer and worked solution

Official answer: 100

Reactances $X_L=2000\times0.01=20$ Ω, $X_C=\frac1{2000\times25\times10^{-6}}=20$ Ω: resonance, $Z=R=100$ Ω.

Answer: 100

Topics:LCR circuits and resonance
