Study Notes

Electric Current

The movement of electrons through a conductor.
A cell causes the flow of electrons.
Electrons always flow from the negative terminal to the positive terminal.
Conventional current flows from the positive terminal to the negative terminal.

Electric Circuit

A continuous and closed path of an electric current.
A circuit where resistors are in parallel 1/Rp=1/R1 + 1/R2 +1/R3.

Components of Electric Circuits

Electric cell: A device that provides electrical energy.
Battery: A group of cells connected together to provide a larger voltage.
