NCCER Electrical Level 1 Module 3-Solved
Ammeter - ANSWER-An instrument for measuring current
Ampere (A) - ANSWER-An electrical unit of current
Atom - ANSWER-The smallest particle to which an element may be divided and still
retain the properties of the element.
Battery - ANSWER-A DC voltage source consisting of two or more cells that convert
chemical energy into electrical energy.
Circuit - ANSWER-A complete path for current flow.
Conducter - ANSWER-A material through which it is relatively easy to maintain an
electric current.
