What name is used for a high power variable resistor?
potentiometer
How does a rheostat make a current high?
A rheostat is a variable resistor that can increase or decrease the resistance in a circuit. By increasing the resistance in the circuit, the rheostat limits the flow of current, causing it to become higher in the parts of the circuit where the resistance is lower.
When to use a rheostat?
Depending on the situation. The purpose of the rheostat is use to change the resistance of the circuit. The rheostat is use to define Ohm Laws the 2nd situation is use to find out what the fixed resistor's resistance. 3rd purpose : used to control the resistance of circuit. eg Radio
What causes the blower on a 2001 Chevy Silverado to work on high but not on low?
the blower fan rheostat usually located in blower box is like a resistor that draws energy from the blower fan supply to slow it down and there is a high speed fan relay for the fastest speed. So your rheostat is not working
Is it possible to apply voltmeter across a variable resistor?
Of course. A good voltmeter can be applied across anything, since its impedance is high and its presence has no effect on the operation of the circuit. When it's connected across a variable resistor, the voltmeter most likely reveals a changing voltage as the resistor is varied.
How does a rheostat work?
A rheostat is simply a variable resistor. It is engineered so a "wiper" travels along the resistor carbon path. There is minimum resistance at one end of the path, and maximum resistance (what maximum value the engineers made into it) at the other end. Rheostats come in many values such as "0 to 1000 ohm", 0-1000 ohm, 0-10,000 ohm, and etc., all the way up to mega-ohm values. Some are designed to work on 0-5 watts, 0-20 watts, or larger power versions with resistance wire in them.
Is the highest Either variable first?
The high is power of either variable is the first
Which motor has high starting tourque?
Series motors have the highest starting torque. The torque is proportional to the square of the current, and the starting current is so high it has to be limited by a resistor called a rheostat. Series motos are used mainly on trams and trolley buses.
Do you have a bad switch if heater goes on and off all the time and fan only works on hi?
You most likely have a problem with your blower RESISTOR PACK or rheostat. This is what controls the high, med and low speeds on your heater. Where it is and how to change it depends on your vehicle.
Why does my 92 Mazda 626LX car heater and AC work on lower settings but cut out completely on full power?
Your '92 Mazda 626LX car heater and AC might work on lower settings but cut out completely on full power because of a faulty rheostat. The fan speeds will not work correctly when this part is bad. Generally the high speed function bypass's the blower speed resistor. The high speed function uses a relay instead. I would start with checking the high speed blower relay.
Can a copper wire be used as a variable resistor in a circuit?
Because copper is a very good conductor, it isn't used for making the main body of a resistor. The body must be made of high resistance metals, such as nickel and chrome alloys. Copper is only used for making the connecting leads of a resistor.
