100
An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
What is Alternating Current?
100
An electric current flowing in one direction only.
What is Direct Current?
100
The physical property of matter that causes it to experience a force.
What is Electric Charge?
100
A substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage.
What is Electric Current?
100
A path in which electrons form a voltage or current source of flow.
What is Electric Circuit?
200
A flow of electric charge.
What is Electric Current?
200
A reign around a charged particle or object within which a force would be exerted on other charged particles.
What is Electric Field?
200
Charged objects exert electric forces on each other and how to calculate the strength of that force.
What is Electric Force?
200
A material whose internal electric charges do not flow freely.
What is Electric Insulator?
200
The rate at which electrical energy is transferred by an electric circuit.
What is Electric Power?
300
Circuits or devices using transistors, microchips, and other components.
What is Electronics?
300
Charge conservation is the principle that electric charge can neither be created nor destroyed.
What is Law of conservation charge?
300
Elating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current.
What is Ohm's Law?
300
A closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
What is Parallel Circuit?
300
The refusal to accept or comply with something, the attempt to prevent something by action or argument.
What is Resistance?
400
A solid substance that has a conductivity between that of an insulator and that of most metals.
What is Semiconductor?
400
A closed circuit in which the current follows one path.
What is Series Circuit?
400
Flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.
What is Static Discharge?
400
An electromotive force or potential difference expressed in volts.
What is Static Electricity?
400
A stationary electric charge typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.
What is Static Electricity?
