Electric Current
Voltage Source
A device that creates a potential difference in an electric circuit.
Insulator
A material through which charges cannot move easily.
Conductor
A material through which charges flow easily.
Potential Energy
Energy an object has as a result of its position.
Electric Current
The continuous flow of electric charges through a material. It is complete and unbroken.
Resistance
The measure of how difficult it is for charges to flow through a material.
Ohm
The unit of measure of resistance.
Volt
The unit of measurement of voltage.
The rubber coating is the insulator. The inner wire is the conductor.
What are the conductors, and what are the insulators in an appliance cord?
Material, length, diameter, temperature
What are the four factors that determine the resistance of a wire?
Battery
What is an example of a voltage source?
Potential Difference
What is the difference in electrical potential energy between two places in a circuit?
Charges must flow continuously from one place to another.
What must occur to produce electric current?
A, amp
What represents the unit for rate of current?
They are bound loosely.
Why are conduction electrons able to move throughout a conductor?
