PhysicsInteger+4 / -1Question 60 of 90

An inductor of 0.5 mH, a capacitor of 200 $\mu$ F and a resistor of 2 $\Omega$ are connected in series with a 220 V ac source. If the current is in phase with the emf, the frequency of ac source will be ______ $\times10^2$ Hz.

Your answer

Answer and worked solution

Official answer: 5

In phase means resonance: $f=\dfrac1{2\pi\sqrt{LC}}=\dfrac1{2\pi\sqrt{10^{-7}}}\approx503$ Hz $\approx5\times10^2$ Hz.

Answer: 5

Topics:LCR circuits and resonance
