What is the material used to make resistors?

Question

i know they are conductors with appreciable resistance but do you know the exact name of such substances?

Answer 1

1. Wire Wound
2. Carbon composition
3. Thin Film
4. Metal film

and more (see the ref below)

Answer 2

Traditional 'cake' resistors are made with carbon as the element. Wire-wound resistors utilize a length of wire (often a nickel-chromium alloy) with a very specific resistance value per inch to produce precision values for resistance.
Any and every material may be used to cause resistance: ceramics have always been used to produce resistance in an object, meant to be so high a value as to cause the amount of electricity traveling across to approach zero. Transistors use this concept to assure maximum resistance to current until a voltage condition is met, at which point they transmit current with minimal resistance (nick-named, semiconductors).

Answer 3

Different metals have different degrees of resistivity, the appropriate metal to use do the job. Making a resistor with a value of one ohm is a challenging task, the technician may have to resort to sizing a wire to alter it's cross sectional area, to get the correct result.

Answer 4

It varies.

Each type has its disadvantages. Carbon is used commonly, and is cheap, but is noisy (that is, the resistance fluctuates as current flows a tiny bit and this can be apparent, especially in audio applications). Wirewound is noise free, but has an inductance so is poor at high frequency. Thin film is expensive.

Most commonly, however, resistors are simply strips of doped silicon in an integrated circuit.
