In an LC circuit, what can I use to prevent the capacitor from discharging?

Question

I have an LC circuit, in which the capacitor is charged to a high voltage.

I need to find a way to prevent the capacitor from discharging back to the source. How do I do this?

Can I use a diode? And if so does it matter which side of the capacitor it's on, + or -?

Answer 1

LC? Lauren Conrad?

Answer 2

yes, you can use a diode, and it can be on either side. Make sure the voltage rating of the diode is above your highest voltage, and the current rating will handle charging surges.

But if you are using resonance to charge the cap, a diode will prevent that.
