Photon
|
A small "package" of light that acts like a particle.
|
Charging by conduction
|
Charging an object by allowing it to come into contact with an object that already has an electrical charge.
|
Charging by induction
|
Charging an object without direct and charge.
|
Electrical Current
|
The amount of charge that travels past a fixed point in an electric circuit each second.
|
Conventional Current
|
Current that flows from the positive side of a battery to the negative side.
|
Resistance
|
The ability of a material to impede the flow of charge.
|
Open Circuit
|
A circuit that does not have a complete connection between the two sides of a power source. As a result, current does not flow.

What causes Electromagnetic Force?
|
-
|
Three principles of Electromagnetic force:
|
1) All electrical changes attract or repel one another: like charges repel while opposite charges attract.
2) The force between charged objects is directly proportional to the amount of the electrical charge on each object. 3) The force between charged objects is inversely proportional to the square of the distance between the two objects |
What is voltage?
|
The force of an electric current measured in volts.
