waveforms capacitor voltage / current | All About Circuits

Consider a switch that goes to +5V and a capacitor. When you close the switch, the capacitor will appear as a short and draw high current. As the capacitor charges, and approaches the supply voltage, it draws less current. You saw this this. Now open the above switch, and consider a switch placed across the charged cap.

Confusion On Electric Field Inside Capacitors

There is confusion about the electric field inside capacitors because it is often mistakenly believed that the electric field is zero inside a capacitor. In reality, the electric field is not zero, but rather varies depending on the distance between the plates and the charge on the plates.

Confusion about voltage at negative terminal of capacitor

I have some confusion about the negative terminal of a capacitor. Consider the following. Now, my understanding was that postive charges accumulate at the positive ("top") plate of the capacitor, setting up an electric field within the capacitor which causes negative charges to accumulate at the bottom plate.
