1.
The flow of electric charges along a path
2.
involves the contact of a charged object to a neutral object
3.
a method used to charge an object without actually touching the object to any other charged object
4.
an object, substance or material allowing the flow of an electric charge
5.
a material whose internal electric charges do not flow freely; very little electric current will flow through
6.
type of magnet in which the magnetic field is produced by the flow of electric current.
7.
a device that converts mechanical energy to electrical energy
8.
a machine designed to convert one form of energy into mechanical energy
9.
Negatively charged particles that are found outside the nucleus
10.
positively charged particles found in the nucleus of an atom
11.
The build up of electric charges on an object
12.
A path along which electric charges can flow
13.
A circuit that has a break in its path, will not work
14.
A circuit that does not have a break in its path, will work
15.
a backup pathway that provides an alternating route for the current to flow back to the ground if there is a fault in the wiring system
16.
potential difference in charge between two points in an electrical field
17.
measure of the opposition to current flow in an electrical circuit
18.
describes the way current flows through a resistance when a different electric potential (voltage) is applied at each end of the resistance
19.
visible electrical discharge from a cloud
20.
the sound made by a flash of lightning
