Question

We desire to make an lc circuit that oscillates at 100 hz using an inductance of 2.5 h. we also need a capacitance of:______.

Answer 1

The LC circuit will also need a capacitance of 1.01 μF.

What is capacitance?

Capacitance is the ratio of the amount of electric charge stored on a conductor to a difference in electric potential.

Capacitance needed for the resonance circuit

Xl = Xc

where;

• Xl is the inductive reactance

Xl = ωL

Xc = 1/ωC

ωL = 1/ωC

ω²LC = 1

C = 1/(ω²L)

C = 1/(2πf)²(L)

C = 1/(4π²f² L)

C = 1/(4π² x 100² x 2.5)

C = 1.01 x 10⁻⁶ F

C = 1.01 μF

Thus, the LC circuit will also need a capacitance of 1.01 μF.
