well guys i am quite nooby at electronics but very enthusiastic to learn, i have got couple of questions about capacitor would be grateful to share the answers if u know them.
for the questions below just assume a very simple circuit DC power supply V, connected to a capacitor C and then goes to the ground.
1- how long does it take for a capacitor of C, connected to a DC power supply of V to be charged ?
2-i know the current cant pass through the capacitor with DC power supply, but lets say the capacitor has been fully charged after the time t, then we wanna discharge the capacitor, so how we can do it by discconecting the main DC source right ?
3- so can we say after time t the charged capacitor has obtained the same voltage as power supply V ?
4- how is it possible to calculate the current provided by the charged capacitor obviously we know the charge Q, and the time t is keep changing so it means the current also keep changing i mean going down cuz as the time increases the currect should decrease I=q/t right ?
thanks guys for ur time
cheers
