FM radio stations use radio waves with frequencies from 88.0 to 108 MHz to broadcast their signals. Assuming that the inductance has a value of 4.60 x 10^-7 H, determine the range of capacitance values that are needed so the antenna can pick up all the radio waves broadcasted by FM stations.
_____F (lowest acceptable capacitance)
____F (highest acceptable capacitance)
Find Xl (2PI f L)
then find C such that
Xc= 1/2PI*f*C where Xc= Xl
do it at each frequency end.posted by bobpursley
