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.
How do I replace the line on a Ryobi RY15523A trimmer?
To replace the line on a Ryobi RY15523A trimmer, follow these steps: Turn off the trimmer and disconnect the spark plug wire. Remove the spool from the trimmer head. Cut a length of replacement trimmer line. Insert the line into the trimmer head following the arrows for the correct direction. Wind the line evenly and tightly onto the spool. Reassemble the spool onto the trimmer head. Reconnect the spark plug wire and test the trimmer.
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
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.
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.
How can I change the string on my Ryobi weed trimmer?
To change the string on your Ryobi weed trimmer, follow these steps: Turn off the trimmer and disconnect the spark plug wire for safety. Remove the spool housing by pressing the tabs on the sides and pulling it off. Take out the old string spool and replace it with a new one. Feed the new string through the holes in the spool and secure the ends. Place the spool back into the housing and reattach it to the trimmer. Reconnect the spark plug wire and test the trimmer to ensure the string is working properly.
