Which of the following characteristics of a wire has no effect on its heating capacity due to electric current?

(a) Length

(b) Material✔️

(c) Thickness

(d) Colour

Answer 2

Colour has no effect on its heating capacity due to electric current. Option(d) is the correct answer.

• The heating capacity due to electric current is directly proportional to resistance. Resistance of the wire is dependent on the length of the wire, the material of the wire, and the thickness of the wire.
• The formula for Resistance is  R = ρ L A in which material, thickness, and length of wire are required and resistance is dependent on them.
• So, only color is the characteristic of wire which has no effect on resistance.
