Question 105Electricity & Electronics - QMED

The correct answer is B) material and temperature. The existing resistance of a conductor is primarily dependent on its length, cross-sectional area, and the material of which it is made. The material of the conductor affects its electrical resistance, as different materials have different levels of electrical conductivity. Additionally, the temperature of the conductor can also affect its resistance, as higher temperatures generally increase the resistance of a conductor due to increased collisions between the electrons and the atoms in the material. The other answer choices are incorrect because: A) Inductive reactance and insulation are not factors that directly affect the resistance of a conductor. C) Insulation does not directly affect the resistance of a conductor, but rather, it affects the ability of the conductor to carry current. D) Capacitive reactance is not a factor that affects the resistance of a conductor.
