1C = 6.24 x 1018 e- or p+
Electric Current is the flow of electrons.
- is the time r
LECTURE 2
Review of V, I, and R
Voltage is the amount of energy per charge available to
move electrons from one point to another in a circuit.
Current is the rate of charge flow and is measured in
amperes.
Resistance is the opposition to current and is me
