Im trying to learn electronics but im stuck on capacitors and its driving me insane. I've spend about 2 weeks reading trying to figure out capacitors but since I cant understand what the purposes for them are im having a hard time.
I've read about the primary functions of them but I dont know enough about electronics to know what they even mean when constructing a circuit. Thats why im stuck.
Heres one of the functions which I have a slight idea what it might mean
Another question
Lets say I have a circuit like this
Im guessing the power supply would cause the light to flash on and off in the short space of time it takes to charge the capacitor. Once the capacitor is fully charged will it just stay like that as long the switch is closed? How would you go about discharging it in a simple circuit like that? Would I have to make the circuit much more complex in order to make the capacitor instantly discharge after it reaches it capacitance?

Lets say I have a basic circuit with a power source and a light bulb. My power source gives 20V but by the time it gets to the light bulb its only 15V due to the wires resistance. Lets say 15V is insufficient. If I was to put a capacitor which held 20V before the light bulb that would solve the problem since it would charge to 20V. Is that what they mean when they say "smooth out fluctuating currents" or am I getting the idea?where a
fluctuating DC voltage needs to be smoothed, or, have the ripple taken out.
