Electrostatics
What is electrostatics?
This is when electrically charged particles repeatedly reverse direction, vibrating about relatively fixed positions.
What is alternating current?
The source of magnetic force.
What is motion of charged particles?
A material that has free charge particles that easily flow through it when an electrical force acts upon them.
What is a conductor?
This is equal to 6.25x1018 electrons.
What is one coulomb?
Electric charge is neither created or destroyed. The total charge before an interaction equals the charge after.
What is conservation of charge?
This is when electrically charged particles flow in one direction only.
What is direct current?
Cluster of aligned atoms.
What is magnetic domain?
A material with properties that fall between those of a conductor and an insulator whose resistance can be affected by adding impurities.
What is a semiconductor?
This is the measurement unit for potential energy per unit of charge.
What is voltage?
The transfer of electrostatic charges between objects by rubbing or touching.
What is charging by contact?
Electric force per unit of charge.
What is an electric field?
All magnets have these.
What are north and south poles?
A device that has a pair of parallel conducting plates separated by a small distance and stores electric charge.
What is a capacitor?
This is the measurement unit for resistance.
What is ohms?
What is charging by induction?
The electrical potential energy per unit of charge. Measured in volts.
What is voltage?
A simple meter that detects electric current; made of a magnet that is free to turn.
What is a compass?
A material that does not contain free charge particles and through which charge does not easily flow.
What is an insulator?
This is the measurement unit for electrical current.
What is amperes?
The relationship between electrical force, charge, and distance is known as this.
What is Coulomb's law?
This describes a current in a circuit which varies in direct proportion to the potential difference or voltage across the circuit and inversely with the circuit's resistance.
What is Ohm's Law?
Phenomenon caused by charged particles from Sun storms that get trapped by Earth's magnetic field, and then dip into the atmosphere which create glowing light.
What is the Aurora Borealis or Aurora Australis?
When an atom or molecule has one side that has a slight excess of positive charge and the other side has a slight excess of negative charge.
What is electrically polarized?
This is the measurement unit of electrical charge.
What is a coulomb?
