· 2.18 recall that electric current in solid metallic conductors is a flow of negatively charged electrons Conventional Current
· The flow of "imaginary" positive charges from + to -
· Why? Positive charges are repelled by the positive terminal of the battery and attracted to the negative terminal of the battery
· Symbol "I"
· Used in 90% of exam questions! I
