How many terminals does a variable resistor normally have?

2 terminals. One is connected to the sliding contact. Other is to the coil of wire.

What is the name of A variable resistor with two terminals?

hi, the center terminal (attached to the wiper contact) tied to one of the ends????

Why is there a resistor on a 36v solenoid?

It reduces contact noise by reducing large voltage and current spikes as the relay is opened and closed, called a snubbing resistor. Before the age of solid state controllers, there were no resistors across the solenoids. The purpose of the resistor is to provide a charging voltage for the capacitors inside the solid state contoller. Without the resistor it would take several seconds for the (50,000 microfarad) capacitor to charge and the equipment to run. With the resistor the capacitors are charged while the solenoid is open and the equipment is ready to run at all times.

What is the function of a cement resistor?

A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).

Voltmeter is connected in parallel with resistor?

A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.

What is 5W15RJ?

it may be a ceramic resistor. If it is a resistor, it'll be about 1 inch in length with 2 contact points. It sounds like a 5-Watt 15-Ohm resistor.

What is the difference between a resistors and variable resistors?

A resistor is a metal or compound that does not conduct electricity very well. It is used to reduce the amount of current going through a circuit and converts some of the current into heat. In its simplest form a variable resistor uses the same metals and compounds but spreads them out in a line or arc and uses a metal contact to slide or rotate over the material. One contact is on the metal moving contact and the other contact is at one end of the resistor. Moving the contact changes the distance the current must move through the resistor thus changing the amount of current reduced.

How dimer switsh work?

It works by sending the current through a resistor. As you twist the dimmer switch it changes the length of the resistor and the longer the resistor the more it inhibits the current. So at full brightness the resistor has been totally bypassed as you turn the light down the contact moves further around the resistor making it longer.

Where is the blower motor resistor on a 2004 Colorado?

The blower fan resistor is located in the foot well of the passenger seat (under the glove box). Remove the two screws and pull the resistor down and out. Unplug the resistor and look at the metal contact points. If they are burnt out you might have to replace the plug and resistor. Replacing the plug requires light electrical work involving crimping/splicing wires.

What care should be taken when handling a resistor?

Handling a resistor can be very dangerous and it is important to take extra precaution when handling one. If one is are unsure of what to do then they should contact a professional that knows what they are doing.

How do you change the coil resistor on a 1988 raider?

the coil resistor is a ceramic block on the top of your coil, you just remove the wires attach to it, put some grease on the bolts(on the new one) that attach the wires, and put it back together, to see if your resistor is faulty, just run a wire from 1 pole to the other, make sure you have a good contact.

Who invented the resistor?

Otis F. Boykin invented the wire precision resistor and the electrical resistor.
