What you have here is a classic LC tank circuit. This is basically guaranteed to oscillate. Changing the sizes of the inductor and capacitor will change the frequency and adding a resistor will damp the oscillation if it''s large enough. It might help if you hang a load off of that transformer so the cap has something to discharge into. Right

6 FAQs about [What can capacitor discharge transform]

How does a capacitor discharge?

Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.

How does capacitance affect the discharge process?

C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, V C. Conversely, a smaller capacitance value leads to a quicker discharge, since the capacitor can't hold as much charge, and thus, the lower V C at the end.

What is discharging a capacitor?

Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.
