and they were talking about the concept of an electric pendulum and I did not get the concept of an inductor and capacitor in one circuit.

First I am very sorry for that awful long text, if you like, skip to the pictures. I just wanted to give you my "explanation" of capacitors and inductors because I clearly messed something up in the way they function. Thanks for the help tho!

First I will try to describe a capacitor and inductor in a circuit, because there clearly must be a mistake in my explanation:

Capacitor charging and the effect on the circuit (just power source and a capacitor):

- A capacitor is resisting changes in voltage and is dissipating power. This power gets stored inside the capacitor until the voltage equals that of the power source

- The effect of charging results in the total voltage is decreasing because the potential difference between the capacitor and the battery is getting less and less over time until its 0, thus current is decreasing as well because there is less "push" to move electrons

Capacitor discharging and the effect on the circuit (just power source and a capacitor):

- A capacitor is resisting changes in voltage and is supplying power. Voltage is decreasing because the electrons are leaving the negative charged plate trying to balance the potential difference, thus current is decreasing as well because there is less "push" to move electrons

Inductors charging and the effect on the circuit (just power source and a inductor):

- The inductor is resisting changes in current but as time moves one the inductor is resisting less current, thus greater voltage at each end of the inductor. Again, current and voltage increasing until fully charged

Inductors discharging and the effect on the circuit (just power source and a inductor):

- The inductor is resisting changes in current thus supplying a voltage to keep current constant. The inductor is discharging, thus less current through the inductor resulting in less voltage.

Again, current and voltage decreasing until fully discharged

Alright, my explaining is done (I think I messed some things up with the capacitor). Let get to the actual page in the book (122)

( I agree)

(I agree)

(I agree)

(Where is the voltage coming from? Is it the voltage in the capacitor? Why is the current decreasing while voltage is increasing?)

(Why is current at 0 while the voltage is at its peak? Phase shifting? But how?)

And so on, but I am clearly missing the big picture its so frustrating I feel so stupid
