Physics Help II

Tue Nov 18, 2003 12:40 am

Here we go again:

A Radio Inductor: You want the current amplitude through a inductor with an inductance of L (part of the circuitry for a radio receiver) to be I when a sinusoidal voltage with an amplitude of V is applied across the inductor.

Using those three variables, what frequency is required?

Hopefully someone can help me.

Thanks,

Matt

Impendance of inductor is Z=L*w
(w is angular velocity)

w=2*pi*f

so put that in Ohm law Z=U/I and you get your answer

Yes I was able to figure it out a few hours ago, and you are correct, thank you so much!!
