The relationship between voltage, current, and resistance.
What is Ohm's Law?
100
The study of static electric charges.
What is Electrostatics?
100
The wire connected from the load to the positive end of the battery.
What is the neutral wire?
100
A device used for detecting the presence of charge.
What is an Electroscope?
100
a unit in which you can measure aAn electric current that always moves in one direction.
What is a Direct Current (DC)?
200
Friction, induction, conduction.
What are the ways objects become charged?
200
Electricity that does not move.
What is static electricity?
200
The unit used for electric meters. The amount of energy transmitted by one thousand watts of power over a period of one hour.
What is Kilowatt Hour (kWh)?
200
Bringing the electrons back to its original state, making it neutral.
What is Grounding?
200
When the energy is used, like going across a light bulb.
What is a voltage drop?
300
When the negative electrons in the clouds are attracted to the positive in the earth.
What is lightning?
300
Like charges repel each other and unlike charges attract each other.
What is The Law of Electric Charges?
300
Provides energy for the circuit.
What is the load?
300
A material that allows electrons or heat to pass easily through them.
What is a Conductor?
300
The rate at which energy is transferred or the rate at which work is performed, defined as work per unit of time.
What is Power?
400
Cost efficient, and better for the environment.
What are the two benefits for using electrical energy?
400
A material that does not allow electric charges or heat to move frely on or through it.
What is an Insulator?
400
If the current is higher than this value, the person cannot let go of the object giving the electric shock.
What is the "Let-Go Threshold"?
400
Rubbing items together will transfer electrons making them charged.
What is Charging by Friction?
400
The unit by which current is measured.
What is an Ampere?
500
A shock.
What is electrical discharge?
500
An atom with a positive or negative charge due to loss or gain of an electron.
What is an ion?
500
A circuit without a load.
What is a Short Circuit?
500
The process by which an object having an electric charge produces the opposite charge in neighbouring object without actually touching it.
What is Charging by Induction?
500
A unit in which you can measure the energy of charges delivered by a cell.
What is Voltage?
