A15.0-μf capacitor is charged by a 130.0-v power supply, then disconnected from the power and connected in series with a 0.280-mh inductor. part a calculate the oscillation frequency of the circuit. express your answer with the appropriate units.

The resonant frequency of a circuit is the frequency at which the equivalent impedance of a circuit is purely real (the imaginary part is null).

Mathematically this frequency is described as

Where

L = Inductance

C = Capacitance

Our values are given as

Replacing we have,

From this relationship we can also appreciate that the resonance frequency infers the maximum related transfer in the system and that therefore given an input a maximum output is obtained.

For this particular case, the smaller the capacitance and inductance values, the higher the frequency obtained is likely to be.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

reserve is the answer
