The charge of an electron is -1.6 x 10^-19C.
The formula for current is : Current = Charge/time or I = Q/t
1. If 8000 C of charge pass through a section of wire in 2 minutes, what would the current be?
2. A current of 55 Amperes through a wire over 5 seconds will have how much charge pass through it? how many electrons made up that charge?
