Suppose a coil and capacitor are connected in series, with jXL = j 40 and jXC = −j70, and the coil has an internal resistance of 10 Ω.
Suppose the frequency of operation is 12.5 MHz.
This circuit will exhibit resonance at
a. some frequency below 12.5 MHz.
b. some frequency above 12.5 MHz.
c. 12.5 MHz; it is resonant under the conditions stated.
d. any and all frequencies.
e. no frequency, because of the internal resistance.
