Function of trimmer resistor?
The trimmer resistor is a calibration device used to correct (trim) the resistance of some other resistor. An example might be the feedback loop of an op-amp in common mode. If you wanted a gain of two, you might use a resistor divider with a two to one ratio. Resistors have tolerance, however, so the stated value will not be exact. You place a trimmer resistor in series with one of the other resistors, picking the value so that, if the two other resitors were exact, the trimmer is set to midpoint, and that the trimmer's range covers the expected tolerance of the other resistors. Then you calibrate the circuit to the expected gain using the trimmer.
What is a trimmer resistor?
A trimmer resistor usually called a trim pot is a small variable resistor it is used in circuits to do preset it is trimmed with a trimmer screwdriver it is made up with a round fiber disc with a layer of carbon with a wiper that run on the carbon layer to change the resistance it always have 3 connecting pins where the center one is connected to the wiper and the other two to opposite ends of the carbon strip.
How do You restring a Honda weed trimmer?
You remove the bottom cover off the weed trimmer, and remove the tangled old wire. Insert the new wire into the side of the trimmer and wrap it around the black spindle.
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
How do you add key-less entry to a '00 Alero?
It is a single wire GM system. You have to connect the white wire (of the master switch) to the green wire(keyless system) then solder a 1.5 Ohm resistor to the white (master switch) wire which is then connected to the resistor the other end of the resistor is connected to the yellow wire(keyless system). ______white_______Green_______>Resistor 1.5K_________yellow
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
When and by who were resistors made?
Otis F. Boykin invented the wire precision resistor and the electrical resistor. In June 1959, he got the first patent for the wire precision resistor and in June 1965, he got his patent for the electrical resistor.
What is with the seven wire replacement clip on the hvac resistor on a 2002 trailblazer?
It should be called the auto HVAC blower motor resistor wire harness. Goes from the auto climate blower motor resistor to the blower motor.
Why should care about resistor temperature increase?
hen the wire inside the resistor will melt and the circuit will be broken
Do you use resistor spark plugs with resistor wire plug ends?
No, Using a resistor spark plug with resistor wires can create too much resistance for the ignition system.
Does 1968 Chevelle have a resistor inline to distributor?
yes it should, look for a bare shielded copper wire that goes to the distributor from the outside of the fuse box, that's the resistor wire.
My craftsman weed trimmer runs on the ground but shuts off when you pick it up?
I solved my own problem,my weed trimmer has a on and off switch the wire in the switch had a bare place that was shorting out, by lifting the trimmer I was putting pressure one the bad connection.
