resistor

Found 10 Results for resistor.

Showing 1 to 10.

1. Setback Thermostats
Ideally, you should buy a model with an adjustable "heat anticipator" — an electrical resistor that generates a small amount of heat when the heating system is on.

2. Meter Minding
Lightning can also adversely affect electric meters not equipped with a lightning resistor. Sometimes, a problem can result if a meter is seriously jarred from time to time, perhaps by a passing bus.

3. DC Motors
Although a rheostat is shown in the drawing, indicating a method of speed control, in most appliances a fixed resistor is used to regulate speed.

4. Universal Motors
A resistor may also be inserted in series with the armature and the field windings to help control the speed of the motor.

5. Motor Controls
" Another way of controlling motor speed is by means of a resistor in series with the field or armature or both.

6. The Volt - Ohm - Milliammeter
The ohmmeter circuitry of the VOM is nothing more than a simple milliammeter circuit with a variable (zero control) resistor (Rz) and test-lead connecting points (X and Y) to introduce a resistor of unknown value into the circuit.

7. Other Devices
It consists of a 9V transistor battery, a 100-ohm resistor, a 1.6V, 16 mA LED (light-emitting diode), and a female ac receptacle.

8. Hand - Held Dryer
The heater is used as a resistor to drop the voltage to approximately 9V ac and feeds the rectifier to produce the 9V, dc.

9. Electric Heaters
The fan switch employs a resistor to reduce the fan motor rpm. On high the switch is closed.

10. Air Purifiers
The resistor limits the current to the transformer and is secured to the inner shell by a screw. The filter and fan switches are removed after the inner shell is removed.
