-Any power supply gas current flow which moves from the positive terminal(RED) to the negative trminal(BLACK)
-The power supply supplies a centain amount of electrical pontential energy
-Electric current involes electrons repelling one anthor and passing through a conductor
-The symbol "I", represents the rate of charge flow
-The energy delivered to the load depends on the potential and the current
-If the path is more difucult, there will be more opposition to flow
-Electrical resistance is a material's opposition to the flow of electric current and it's measured in Ohms
-There are more useful when the static state electrons are made to transfer energy
- The currennt flows in a single direction from the power supply through the donductor to a load is called DC(Direct Current)
