| 1. | The variable resistors ( R6 and R7 ) controlled the motor speed.
|
| 2. | A PIN diode, suitably biased, therefore acts as a variable resistor.
|
| 3. | I understand that modern dimmers are more efficient than old variable resistor style.
|
| 4. | An external, variable resistor controls the motor speed.
|
| 5. | It may be a fixed or variable resistor.
|
| 6. | The depth control limits the amount of application the variable resistor has on the audio signal.
|
| 7. | The input was six potentiometers ( variable resistors ) each having a dial with 26 letters.
|
| 8. | The lamps'brightness was controllable with a variable resistor.
|
| 9. | The joystick potentiometer acted as a variable resistor.
|
| 10. | It's like a variable resistor, and can store information like 1's or 0's due to it's resistance.
