Hey guys, I know I have left some topics unanswered. I'm working on reading more about electricity to improve my understanding. Thank you for having helped me in earlier topics, I have certainly begun to comprehend a lot more.
Now, right to the question. So I got a capacitor being charged up by a battery. I know that capacitors are basically composed by two plates separated by an insulator. Once the circuit is closed, one of the plates gets negatively charged and the other one gets positively charged until there is a voltage equal to that of the battery.
Is voltage in the capacitor caused by the electric field between the plates?
If I take the charged capacitor out of the circuit and connect its terminals to a bulb for example, does it get discharged because negative charges flow to the positive plate through the bulb, but not through the space between the plates?
Does current stop flowing in a circuit once the capacitor is completely charged?
Why do electrolytic capacitors are electrolytic? I mean, I know an electrolyte allows current to flow for example in water, by placing salt in it. The electrolyte is between the plates, but there should be an isolator instead, not a conductor.
Thank you in advance. Please correct me if I'm wrong in any of my suppositions.
