​

Current:  Amount of charge moving through a wire or other media.  The moving particles are often electrons, but can be charged molecules or particles, for example.  Although the most common moving charge (especially in wires) is electrons and these are of course negative, current is by convention expressed although it is positive charges that were moving.

​

Voltage:  Electrical potential Energy per unit charge

​

Kirchhoff's Laws:  Rules useul for solving electrical circuit problems as they let you construct equations regarding the voltage and current in portions of the circuit.

 

Oersted's Principles: Laws that relate magnetic fields related to electrical current
