|
|
Coulumbs law |
Electric force between 2 charges is proportional to the product of the 2 charges |
|
|
Magnetism |
(Force off attraction) |
|
|
Magnetic fields |
Exists whenever electric charges are moving. When they are moving a Torque results |
|
|
Generator |
Device that converts mechanical energy, such as water coming down a water fall, into electric energy |
|
|
Electric potential energy |
Can be compared to the gravitational force associated with an object's position. Because of the force the object has potential energy. |
|
|
Potential difference |
Change in electrical potential energy |
|
|
Transformer |
Device that changes the potential difference of electricity |
|
|
Voltage |
(Another term for potential difference) Measure of the electrical energy available |
|
|
Voltometer |
Measures the potential difference between 2 parts in an electric circuit |
|
|
Current |
Electricity moving through a circuit |
|
|
Ampere |
Unit used to measure electrical current |
|
|
Ammeter |
Device that measures the current going through any specific point on the circuit. The way by which the ability to flow through a circuit is limited. |
|
|
Resavor |
Lowers voltage |
|
|
Series circuit |
Has all its resistors in a row so that all current must travel through all resistors |
|
|
Parallel circuit |
Has all its resistors arranged side by side, so that they are all at the same voltage. |
|
|
Electrical power |
Power = Voltage X Current |
|
|
Watts |
Watts = Voltage X Amperes
Power is measured by watts |
