The variable capacitor in the tuner of an AM radio has capacitance of 1800pF when the radio is tuned to a station at 550 kHz. a) What must be the capacitance for a station at 1600 kHz?
I found the frequency first and then am I supposed to setup the 1600 equal to the frequency to find the capitance.
f = f = w / 2π = 1 / (2 π √ LC )
550000 Hz = 1 / (2 π √L * 1.8E-9 Hz)
= H
Do I just use algebra to isolate for L and then use my new inductance to my find my new C.
Am I going to need to use my period? None of these methods seem to be working..
T = 1/f
thanks
