Show that 2.6 < e < 3.

Calcualte the temperature at which the resistance of a conductor becomes 20% more than its resistance at 27^@C . The value of the temperature coefficient of resistance of the conductor is 2.0 xx 10^-4 K^-1

A conductor of length l is connected to a d.c. source of potential V. If the length of the conductor is tripled by streaching it, keeping V constant, explain how do the following factors vary in the conductor. 1) drift velocity 2) resistance
