Resonance and Tuning Methods
Fig. 1 shows an air-wound coil and a mechanical tuning capacitor. The induc- tance value of the coil is not changed in this arrangement. Rather, the capacitor is ad- justed to change the resonant frequency of the coil-capacitor combination. At each setting of the capacitor, we will have resonance (canceled reactance) at a different

electromagnetism
If the coil is shorted, the current could be high, but the resistance could be very low, so the losses could be low as well - close to zero, if a coil was a superconductor. From the above, it follows that, for a given setup, there must be some coil load resistance, which will cause maximum losses and, therefore, maximum damping.
10.14: Discharge of a Capacitor through an Inductance and a Resistance
The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor. Thus while the electric field in the capacitor diminishes, the magnetic field in the inductor grows, and a back electromotive force (EMF) is induced in the inductor. Let (Q) be the charge in the capacitor at some time.

Consider the capacitor connected directly to an AC voltage source as shown in Figure 23.44. The resistance of a circuit like this can be made so small that it has a negligible effect compared with the capacitor, and so we can assume negligible resistance. Voltage across the capacitor and current are graphed as functions of time in the figure.

Effects on DC SQUID characteristics of damping of input coil
The possibility of improving dc SQUID performance by damping the input circuit resonances caused by parasitic capacitances is studied experimentally.

Once the tank capacitor is found, add capacitance across it until the ringing frequency is cut in half. The ringing frequency is cut in halve by squaring the total capacitance value, then adding a series resistance to the capacitor until an acceptable damping is reached.
