Question

Hello people ~

A current passes through a resistor. If K₁ and K₂ represent the average kinetic energy of the conduction electrons and the metal ions respectively then

(a) K₁ < K₂

(b) K₁ = K₂

(c) K₁> K₂

(d) any of these three may occur
​

Answer 1

K1>K2

Step-by-step explanation:

The main reason behind this is law of conservation of momentum

• Momentum can neither be created nor endorsed.

But

the factor drift velocity affects the scenario.

Drift velocities of electrons is way more than velocities of ions so

• K1 is greater than K2
