Term
Charged particle
Definition
particle with an electric charge
Term
Law off electric
Definition
Says that opposites attract: positively charged objects are attracted to negatively charged objects; objects with the same charged repel (push away) one another: two negatively charged objects will push away from each other... so will two positively charged objects
Term
Static electricity
Definition
When charges build up on an object
Term
Electric discharge
Definition
When built up charges (static electricity) leave the object so that it is no longer charged
Term
Conductors
Definition
Substances that carry electrical energy well
Term
insulators
Definition
Substances that don't carry electrical energy well
Term
semiconductors
Definition
An element or compound that conducts electric current better than an insulator but not as well as an conductor
Term
resistance
Definition
When a substance doses carry electricity but it slows it down
Term
circuit
Definition
A circular path that electrical charges flow through
Term
load
Definition
Anything that can be made to work by electricity your television and the bulb in your lamp would be called the load
