The circuit has an input AC voltage with amplitude of 12 V, while the output
voltage was measured across the 8 resistor. It was found that the amplitude
of the output voltage varies with frequency, hence a wide range of frequencies
were used in order to understand the characteristics of such circuit. Following
from there, it was found that at 5000 and 50,000 Hz, the amplitude of the
output voltage was 5 times lower than that of the input voltage.

Using the clues provide above, analyse the RLC circuit in order to calculate
the values of following parameters:
(a). Inductance, L
(c). Resonance frequency, f, (not angular frequency)
(e). The range of frequency, Af (just the magnitude of the range) of which
the RLC circuit is operating at 50% of its maximum output power.
