| Question | Answer |
|---|---|
| a build up of negative charge on an object; is not freely moving BUT can jump from one object to another if the charge builds up in excess | static electricity |
| a stream of moving electrons; is freely flowing through an object, usually a conductor | current electricity |
| electricity that is constantly changing direction as it travels | alternating current |
| electricity that travels in only one direction | direct current |
| a closed path in which electrical charges can continuously move | circuit |
| gives the electricity only ONE possible path to follow | series circuit |
| gives the electricity more than one path to travel along | parallel circuit |
| rate at which charge flows past a point on a circuit | current |
| positive or negative end of a battery | terminal |
| must be disposed of once the chemical reaction inside has ended | primary battery |
| when the chemical recation inside has ended, it can be recharged so that the reaction is reversed and can proceed again | secondary battery |
| measure of the potential energy in Joules supplied to each Coulomb of charge; also called electric potential | voltage |
| refers to how well an object resists or impedes the flow of an electric current through it | resistance |
