an electronic device that stores electrical power energy
a material that electric current can easily move through, such as metals
motion in a gas (as air) or a liquid in which the warmer portions rise and the colder portions sink
the amount of electric charge flowing past a specified point per unit of time. The unit for current is ampere (A).
the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy.
a device that produces electricity
electric current is directly proportional to voltage and inversely proportional to resistance. I=V/R
