30
Most of the electricity you use daily consists of a flow of tiny, negatively charged particles called
Electrons
31
Electric current moves along a path called a
Conductor
32
Any electrical appliance activated by the flow on am electric current such as a facial steamer is known as a
Load
33
Materials that best transport electricity are called
Conductors
34
Since silver and copper transmit electricity, they are
Conductors
35
Which of the following materials are considered a conductor
Water containing ions
36
Materials that do not allow a current to pass through them are called
