Question # 1

A potential difference is applied across the ends of a copper wire,What is the effect on the drift velocity of free electrons by decreasing the length and temperature of the wire?

  • Ans 1: By decreasing the length and temperature of wire the value of resistance in the wire also decrease which cause an increase in the value of current,Hence the drift velocity of free electrons also increase.

Question # 1

What does the equation H=I2Rt show?

  • Ans 1: This equation show the heating effect,During their motion free electrons collide frequently with the atom of metal.on each collision they transfer some of their kinetic energy to the atom with which they collide.And these collisions produce heating effect in the wire.
