A resistor is any material that exhibits a resistance. Although copper wire is very low resistance, there is still an element of resitance. Other wire has higher resistance and high power resistors are often made from a coilf of wire. Most resistors use carbon to provide the resistive path. Newer products include plastics, doped with metal. The faders on expensive sound mixers use plastic resistors because they are very stable, hardwearing and tend not to suffer from the crackling noise that volume controls sometimes generate as they get older.

What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
Is a battery a resistor if not what is?
No, a battery is not a resistor. A battery provides electrical energy, while a resistor is a component that restricts the flow of current in a circuit.
How does current change through a resistor?
When an electric current flows through a resistor, the resistor resists the flow of the current, causing a decrease in the current. This decrease in current is proportional to the resistance of the resistor, as described by Ohm's Law.
What is the rule for voltage across each resistor?
The rule for voltage across each resistor in a series circuit is that the total voltage supplied by the source is equal to the sum of the voltage drops across each resistor. In a parallel circuit, the voltage across each resistor is the same and equal to the source voltage.
Who made the first resistor?
Otis f.boykin made and invented first the resistor
Where is the resistor in an electric stove?
What is a electric stove resistor made
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 ia a ballast resistor made of?
A ballast resistor is typically made of ceramic or a special heat-resistant material. This material is chosen to withstand high temperatures generated by the electrical current passing through the resistor.
What type of fixed resistor is made from a compound of carbon graphite and resin bonding material?
A carbon composition resistor is made from a compound of carbon graphite and resin bonding material. This type of resistor has a cylindrical shape and is used for applications requiring high stability and low noise levels.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Swamping resistor is made up of?
Swamping resistor is mostly made of manganin or constantan because these materials have temperature coefficients very close to zero thus there is a very less change in the resistance of these materials with change in temperature.
What are resistors in IC made of?
Resistor in IC are made of semiconductor structures in a manner similar to transistors and PN junctions
Is it true that the higher a resistance value the higher the voltage drop?
Greater value resistor will absorb more voltage than smaller value. The more voltage absorb with same value current flow, the larger body mass resistor will require. Body size depends on type of resistor (material resistor is made of).
Is Light dependent resistor an example of resistor?
yes, a variable resistor
In roughness measureing system what is RMS value?
RMS value is defined as "The amount of ac supply required to make same heat effect in resistor , which is made by dc current, in that resistor"
What is the meaning of load resistance?
"Load resistor" is a discriptor, not a value. Any resistor can be a load resistor if it is the proper value and power for your application. So if you want a load resistor by itself, that makes no sense. A load resistor is a resistor selected for a specific purpose. For example, it you want to put a load on an audio amplifier made to drive an 8 ohm speaker to 50 watts, then your load resistor would be a 8 ohm 50 watt resistor. If you want a load resistor to terminate a 50 ohm line, you would need a 50 ohm resistor, although in this case, you probably want one that is part of a co-ax connector. A load resistor for an op-amp output is typically 2k, since most op-amps are rated for 10 volts at 5 mA. Etc, etc.
