A 40.0-μFcapacitor is connected across a 60.0 Hz generator. An inductor is then connected in parallel with the capacitor. What i
amm1812

Answer:

The value of the inductance is 175.9 mH.

Explanation:

Given that,

Capacitor C= 40.0\ \muF

Frequency = 60.0 Hz

The inductor and capacitor is connected in parallel, the voltage across each of these elements is the same.

We have,

V_{L}=V_{C}

Using ohm's law

I_{rms}\times X_{L}=I_{rms}\times X_{C}

X_{L}=X_{C}

2\pi f L=\dfrac{1}{2\pi f C}

L=\dfrac{1}{4\pi^2\times f^2\times C}

Put the value into the formula

L=\dfrac{1}{4\times\pi^2\times60.0^2\times40\times10^{-6}}

L=0.1759\ H

L=175.9\times10^{-3}\ H

L=175.9\ mH

Hence, The value of the inductance is 175.9 mH.
