Question

In an oscillating L-C circuit in which C=4.00 micro F, the maximum potential difference across the capacitor during the oscillations is 1.5 V and the maximum current through the inductor is 50.0 mA
What is the inductance L? Plz give a detailed solution or atleast a hint to how to solve it.Thanx in advance

Answer 1

any1 Here? I m totally confuzzled with this question,the things i know are -
1) \[f = 1/2\pi \sqrt{LC}\]
2) e = Ldi/dt= q/C
Cant get a clue of how to find L
:| need a hint ,

Answer 2

potentiel difference across a capacitor=q/C
u can find maximum charge on capacitor from this
now use the equation-----> Ldi/dt=q/c.
i m not that sure but see if this can help u a bit

Answer 3

yeah i was thinking of using that equation , but again i dont know the value of di/dt

Answer 4

use energy formula.
the total energy in an L-C circuit is=(1/2)CV^2=(1/2)LI^2 (I=maximum current)
from here u can find L

Answer 5

Yeah , thats right Approach ,Thanx , almost forgot the Energy concept , Thanks a lot :)
