Tank Circuit With Resistor. Use a large resistor in series with the function generator to mimic a current source. One final example is shown in figure 13.
Due to the absence of a resistor in the ideal form of the circuit an lc circuit consumes no energy. The same charge movement can be observed in the leyden jar by savary. The circuit can act as an electrical resonator an electrical analogue of a tuning fork storing energy oscillating at the circuit s resonant frequency.
It is analogous to the action of a shock absorber in dampening the bouncing of a car after striking a bump in the road.
Use a large resistor in series with the function generator to mimic a current source. Lc circuits are used either for generating signals at a particular frequency or picking out a signal at a particular frequ. Because inductive reactance increases with increasing frequency and capacitive reactance decreases with increasing frequency there will only be one frequency where these two reactances will be equal. In an lc oscillator circuit the filter is a tuned circuit often called a tank circuit.
