Question

When temperature increases, thermal speed of electrons in a conductor??​

Answer 1

Answer:

As the temperature increases, the thermal agitation of the electrons increases thereby, increasing the number of collisions. Hence, drift velocity of the electrons decreases. (a) In a metre bridge, the balance point is found to be at 39.5 cm from the end A, when the resistor Y is of 12.5 Ω.

Answer 2

Answer:

$increases$
