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.

Using a 741 op amp how do you find the resistors values having a frequency of 1khz to obtain a sawtooth generator wave?
What kind of question is that. What resistors, what circuit are you talking about?
No clock or radio disply 2001 Mercury Villager but the CD changer and radio work just fine?
These radios are notorious for the displays going blank. I have a 1999 Villager Estate that had the same problem. The cause is usaully a set of large resistors on a circuit board inside the radio. The resistors get so hot that the solder connecting them to the circuit board actually melts and they become disconnected. The repair involves opening the radio, finding and resoldering the large resistors. They can be identified by the heat discoloration that they cause on the circuit board. This isn't too difficult, but if you have no experience using a soldering iron, then you may want to take the radio to a friend with a bit of soldering experience.
Hi I have a Hitachi HA-250 and have loved it but recently one of the channels bust and is now completely distorted and horrible to listen to. Any thoughts?
It could be a number of things, but check the 120 ohm resistors (four of them, two per channel) just alongside the heatsink, as well as the four 47 ohm resistors mounted nearby underneath the board (inside little insulating tubes). I have seen these go very high in value, causing distortion.
Why variable resistors are not very reliable?
i find this question rather shallow and pedantic. Clearly the molecular structure of an apple seed is equal to the equilibrium of a ten ton block of iron. Think of it as a quadratic function that has no solution. X is equal to the mass of jupiters moon, io. I hope that clears it up for you. :)
How do you test a blower motor on a 1997 Jeep Cherokee to determine if the resistor or the motor is bad?
spin the motor, if its raspy or rough, any play in it, replace it! i should have done that first! i went through 2 resistors. im bummed!
Do the resistors is made of semi conductors?
no
How do you randomly choose resistors for your voltage divider circuit?
you don't. you calculate resistors required for your needs then select closest available resistors made with acceptable tolerance.
What is modem made out of?
Plastic, solder, and resistors.
What is carbon composition resistors?
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.

What is a non-conductive resistor?
non-conductive resistors are resistors made from materials which do not allow the passage or flow of electric current through them.
Does a toaster have a resistor?
Look inside the toaster when it is toasting. The wires that go back and forth and glow red during toasting are resistors, there is one of these wire resistors on each side of each slot to provide the heat that does the toasting. The wire of these resistors is made of an alloy called Nichrome, made of Nickel and Chromium, that has relatively high resistance. Nichrome is also used in wirewound resistors in electronic devices.
Why do resistors need to be precise?
A: Resistors are never precise they normally come with 5% tolerance. However if precise tolerance is needed one can purchase a precise resistor down to 0,01% or even lower % but these resistors are special and made special for each application
What are those materials of resistors?
most of the resistors commonly used are carbon resistors
What are resistors in IC made of?
Resistor in IC are made of semiconductor structures in a manner similar to transistors and PN junctions
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
