Hi all.
I am having trouble with LC Circuits. It is my understanding, and correct me if I'm wrong, that RLC Circuits include the resistor in order for the oscillation to die eventually, while LC Circuits can in theory and in perfect lossless conditions live forever. It is also my understanding that you can use any capacitor and any inductance/coil to make an oscillation, and the size of the components determine the oscillation frequency. As I read it, puting a capacitor in parallel with a coil should result in a oscillation that would eventually die out after a long period of time (due to the resistance in the wires etc).
I have been trying to create a LC Circuit, but don't seem to create this long oscillation, but rather a small spike, then silence... I've tried different sized inductors and capacitors, but no success.
Using LT Spice I've designed a Circuit that seems to die slowly over time but in real life, I can't reproduce this.
I'm measuring with an oscillator where I connect the probe at one inductor leg and the ground to the other. The setting is to measure DC.
Can someone help a noob?
