non-conductors
A complete electrical current is……. that conducts electricity and provides a return path for the current.
a closed loop
The path of an electric current from the beginning from the generating source through conductors and back to its source is called ……… electrical circuit.
a complete
A constant, even-flowing current that travels in one direction only is commonly known as ……. current
a direct
Rapid and interrupted current, flowing first in one direction and then in the opposite direction, is commonly known as ……. current.
an alternating
A cell phone uses ……. current.
a direct
Paraffin heaters use ….. current.
