Question

specification of fixed resistor​

Answer 1

Answer:

A resistor having a fixed, defined electrical resistance which is not adjustable. In an ideal world a perfect resistor would have a constant ohmic resistance under all circumstances. This resistance would be independent of for example frequency, voltage or temperature.

Specification of Resistor:

✫ Ohm's Rating-

It specifies the value of maximum resistance offered by resistor when it is used in circuit

✫ Power Rating-

The maximum power of a resistance can dispate safetly

✫ Tolerance value-

The percentage variation of resistance value with respect to its marked value

✫ Temperature Co-efficient-

It specifies how resistance value varies with respect to temperature

$\alpha = \frac{ʀt - ʀ0}{ʀ0t}$
