Previous: Voltages in the Series RLC Circuit: Magnitudes and
The series RLC circuit has a resonance where the current takes a maximum
value. This resonance will be sharpest for small values of R, large L
and small C, although the frequency of the resonance depends only on L and
C. Suggested values are 
mH and 
F, since with
these values the resonant frequency is not near the end of a decade on the
signal generator. Any value of R between 10 and 100 ohms will work well -
most of the resistance in your circuit is the internal resistance of the signal
generator. Observe how the voltage across the resistor (and hence the current)
changes as the frequency is changed.
Determine the value of 
for which
the circuit's total impedance is minimized
and compare this with what you would expect
given the values of L and C in your circuit.
Measure the current 
in the circuit as a function of frequency in the
vicinity of the resonance.
