Statement 1: Electric current (flow of electrons) creates heat in a resistor. Statement 2 : Heat in the resistor is created according to the law of energy conservation.
Explain Statement 1 with the help of Statement 2.

Explanation

(1) When electrons flow through a resistor (during flow of electric current) electrons possess kinetic energy.
(2) During the flow of electrons there is a decrease in the kinetie energy of the electrons due to collisions with atoms, tons and molecules.
(3) According to the law of conservation of energy, this decrease in the kinetie energy of the electrons gets converted into heat.
