In an electrical circuit the power dissipation in a resistor will be 1.2 W, which of the following resistor is best suitable to use under this power dissipation.

A carbon film

Refer : Basic Electrical Theory
1/8 Wt to 2 Wt -> carbon film
1/4 Wt –> metal Film
low power –> Thick film
2Wt or more = wire wound
