| alternating current | when electrons first move in one direction and then reverse and move in the opposite direction |
| current | the quantity of electrons flowing, measured in amps (I) (A), may indicate the presence of electron flow |
| electric power | measured in watts (W), one watt= one amp of current flowing through an electric potential of one volt for one second, power loss is proportional to the square of the amperage in a circuit |
| fuse | too much amperage will melt |
| negative electrification | electrons have been added to an object, giving it a net negative charge |
| qualities of electric resistance | may be called impedance, measured in ohms. |
| semiconductor | william shockley, materials can act as conductors OR insulators, generally composed of silicon and germanium, transistors |
| types of circuit devices | circuit breakers, fuses, rheostat (potentiometer) |
