3
|
is a closed circuit in which the current follows one path,
|
|
4
|
is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.

|
6
|
each of the two points or regions of an artificial or natural magnet to and from which the lines of magnetic force are directed.

8
|
is a flow of electric charge.
|

|
|
10
|
a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
|
|
12
|
a complete electrical connection around which current flows or circulates.

|
3
|
a stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.
|
|
5
|
drive or force (an attack or attacker) back or away.
|
|
6
|
a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.
|
|
7
|
a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
|
|
11

14
|
a substance or device that does not readily conduct electricity.
|

a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
|
|
16
|
a roughly circular line, route, or movement that starts and finishes at the same place.
