Question

what are the factors in which efficiency of resistor in a circuit depend upon

Answer 1

$\mathfrak{\huge{\red{\underline{\underline{Answer:}}}}}$

The resistance of an object (i.e., a resistor ) depends on its shape and the material of which it is composed. Resistivity ρ is an intrinsic property of a material and directly proportional to the total resistance R, an extrinsic quantity that depends on the length and cross-sectional area of a resistor.
