|
|
What are the 3 rules of series circuits? |
1. Current is the same at any point. 2. Total resistance is the sum of the individual resistors. 3. Applied voltage equals the sum of the voltage drops. |
|
|
What does the voltage divider formula state: |
The voltage across any particular resistance is equal to the total circuit current times the value of the resistor. |
|
|
What is a voltage divider used for? |
Provides different voltages between certain points. |
|
|
What is voltage polarity? |
The direction of voltage in regards to the direction of current within a given circuit. |
|
|
Describe an earth ground/ground point: |
An object physically driven into the ground. |
|
|
Describe a chassis ground: |
A common point used as a common connection in other parts of the circuit. It is not directly connected to ground, but insulated from ground. |
|
|
What circuits use ground as a common reference point to produce voltages above and below ground? |
Voltage divider circuits. |
|
|
What is above-ground voltage? |
Positive with respect to ground. |
|
|
What is below-ground voltage? |
Negative with respect to ground. |
