Question
Explain flow of current in different conductor.

Answer

  1. A current can be generated by positively or negatively charged particles.
  2. In an electrolyte, both positively and negatively charged particles take part in the conduction.
  3.  In a metal, the free electrons are responsible for conduction. These electrons flow and generate a net current under the action of an applied electric field.
  4. As long as a steady field exists, the electrons continue to flow in the form of a steady current.
  5. Such steady electric fields are generated by cells

Mass of an Oxygen molecule is $5.35 \times 10^{-26} \ kg$ and that of a Nitrogen molecule is $4.65 \times 10^{-26} \ kg.$ During their Brownian motion $($random motion$)$ in air, an Oxygen molecule travelling with a velocity of 400 m/s collides elastically with a nitrogen molecule travelling with a velocity of $500 \ m/s$ in the exactly opposite direction. Calculate the impulse received by each of them during collision. Assuming that the collision lasts for
$1 \ ms,$ how much is the average force experienced by each molecule?
