Tank Circuit With Resistor. 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 broadens the frequency response of the circuit because it carries a part of the line current that cannot be canceled at resonance.
Resistance may be intentionally added to the circuit either in series or parallel for the express purpose of dampening oscillations. The same charge movement can be observed in the leyden jar by savary.

The same charge movement can be observed in the leyden jar by savary. It is analogous to the action of a shock absorber in dampening the bouncing of a car after striking a bump in the road. In the figure a resistor is in parallel with a tank circuit. The resistor r s is called a damping resistor.
