electric circuit -- Why is the switch needed in this capacitor circuit?
Hi,
I have two questions with respect to the picture in the attachment.:
1)
I have read, that the capacitor become charged, when the switch is closed. All right, but why the capacitor doesn't became charged before...
Hi,
I consider a connected conductor. Is it right, that:
1)the potential at any point of the conductor is the same, but
2)the absolute value of the potential isn't zero in general?
I think these statements are true, but I'm not sure about it, especially with the second statement...
