2/17/11 Learning Objectives Charge Current and Voltage Energy and Power Ideal basic circuit element Passive sign convention
2/17/11 Charge Fundamental electric quantity Unit: Coulomb (C) Charge of an electron: qe = -1.602 x 10-19 C Charge of a proton: -qe = +1.602 x 10-19 C It takes many, many electrons to produce a meaningful amount of electric current.

2/17/11 Charge is conserved. This is based on conservation of matter . Electrons and protons are neither be created nor destroyed in an electric circuit. They can only be transferred.
2/17/11 Current Current (i) is the rate at which charge is passing through an area i = q/ t where i = the current in Amperes q = the charge in Coulombs t = the time in seconds 1 Ampere = 1 Coulomb/second
