In an oscillating LC circuit, L = 1.39 mH and C = 4.99 ?F. The maximum charge on the capacitor is 3.98 ?C. Find the maximum current.

Expert Solution

Given that

The inducatnce of the inductor (L) =1.39mH

=1.39*10^-3H

Capacitance of the capacitor (C) =4.99?F

=4.99*10^-6F

The maximum charge on the capacitor (Q) =3.98?C

=3.98*10^-6C

We know that

U=(1/2)LI² =Q²/2C

The maximum curent is

I = Q/?LC

= 3.98*10^-6C/?(1.39*10^-3H)(4.99*10^-6F)

= 47.79*10^-3 A
