| 1. To take a small signal and make it bigger by increasing the
voltage, the current, or both.
2.
3. Two factors needed to create current.
| __a. |
Force to push (voltage). If there is no force, nothing will be
moved. |
| __b. |
The electronis that are pushed. If there are no electronis available
to be moved, there is no flow. Picture an empty stream bed.
An insulator has no electrons available. |
4. Basic units representing current
a. in watter 
b.In Electricity 
5. 1 coulomb = 10000000000000000000 electrons per second
6. .0153 c X 1018 = 1.53 X 1016 = 15300000000000000
electroncs per second

a. |
Pressure in the hose comes rom the city water system. |
|
b. |
Pressure in electronic systems is called voltage. |
|
c. |
Squeezing the hose decreased the cross section area the water can flow
through. The result is extra resistance, restricting the flow.  |
|
d. |
Increasing resistance restricts the flow, slows the current. |
|
e. |
Current decreases as the resistance increases. |
|
f. |
Current increases as the resistance decreases. |
