mean free path:the average distance covered by an electron between two successive collisions is  calles mean free path.
for manganin, temperatur co-efficient of resistance is very very less.so charge in resistance of the manganin wire with temperature is almost neglisible.so it is used to standed resistance.

In physics, the mean free path is the average distance traveled by a moving particle (such as an atom, a molecule, a photon) between successive impacts (collisions), which modify its direction or energy or other particle properties.
