Definition
| A�resistor�is a two-terminal�passive�electronic component�which implements�electrical resistanceas a circuit element |
|
|
Term
| how do you test resistors |
|
Definition
|
|
Term
| what is the function of a resistor |
|
Definition
|
|
Term
|
Definition
| The�electrical resistance�of an�electrical element�measures its opposition to the passage of anelectric current |
|
|
Term
| what is the unit of resistance |
|
Definition
|
|
Term
| how does a resistor function |
|
Definition
| When a voltage V is applied across the terminals of a resistor, a current I will flow through the resistor in�direct proportion�to that voltage |
|
|
Term
| what is one Mnemonic for remembering the sequence of the resistor color code |

|
|
Term
| what does the power rating indicate |
|
Definition
| the amount of power a resistor can safely dissipate |
|
|
Term
| how much power does most resistors in circuits dissipate |
|
Definition
| usually no more than 1/4 and sometimes 1/2 watt |
|
|
Term
| if the average power dissipated by a resistor is more than its power rating what happens |
|
Definition
| damage to the resistor may occur permanently altering its resistance and causing erratic behavior or circuit failure |
|
|
Term
| what is the temperature coefficient |
|
Definition
| the change in resistance as the device warms |
|
|
Term
| what does the tolerance rating indicate |
|
Definition
| the�precision�of the resistor given as a percentage. Resistors within tolerance will only vary their resistance by the amount of tolerance |
|
|
Term
| how should the power rating of resistors be chosen |
|
Definition
| it should be about twice the power consumption needed |
|
|
Term
| in order to measure a resistor of less than 1 ohm with accuracy what does it require |
|
Definition
| a four terminal connection |
|
|
Term
| since a resistor acts as a current limiter what is one way it can be seen as in a plumbing analogy |
|
Definition
|
|
Term
| if a capacitor is a storage device how can adding a resistor add a time delay |
|
Definition
| since a capacitor could be seen as a bucket and a resistor as flow constrictor, constricting more flow would increase the time it takes to fill the bucket |
|
|
Term
| what are th three types of resistor noise |
|
Definition
| thermal, contact, and shot noise |
|
|
Term
| what is thermal noise directly proportionate to |
