Voltage is the electrical potential difference between two points
|
Voltage in the real world:
some places you may have seen volts are: • in batteries (9v, 1.5v, etc.) • in your wall sockets (110 or 220) • Chevy volt (an electrical car) |
|
|
current is the flow of electrical charge from one place to another, often moving electrons in a wire. We measure this in amps or amperes
|
How ever fast it takes the electrical charge to get from the high lake to the low lake
|
|
|
the resistance is how easy or difficult it is for the current to flow from one place to another.
|
higher resistance means its harder to flow. the unit of resistance is the ohm.
|
|
|
Ohms Law - The current in a system is equal to the voltage of the system divided by the resistance
|
the water flows from one body of water to the other based on the difference in height between them two, and how easy it is to get from one to the other.
