| Continuity tester | Is used to trace the flow of electricity in individual wires in a wire harness or other electrical conponents. |
| Dead cell | Is when the zinc in a Dry cell is finally eaten away, the cell can no longer produce electricity. |
| Dry cell | Chemical energy produces electricity by using electrolyte (paste) in the cell reacts with zinc can and the carbon rod. |
| Ferrous metals | Metals that have iron or steelas part of their makeup. |
| laser | Light amplification by stimulated emission of radiation, which |
| Magnetic declination | The difference between the geographic and magnetic poles. |
| Magnetic north | Is the attracting of the north seeking pole of the compass needle. |
| Magnetism | The invisible force that attracts certain materials such as steel. |
| Nonferrous metals | Not made of iron. |
| Photoelectric cell | A cell that will change its resistance when struck by light. |
| Piezoelectricity | The ability of some types of crystals to produce a voltage when put under certain types of stress. |
| Specific gravity | Is a comparison of the density of the acid with the density of water. |
| Thermocouple | A device used to measure temperature by the use of two dissimilar metals which are joined at the point where the measurement is being taken. As heat is applied, the voltage generated can be read on a meter calibrated in degrees. |
