1.	Explain the Joule\'s law of heating and derive its formula.
Answer» \xa0Work done in carrying a charge Q through a potential difference V is given as\xa0Also, Q = I t\xa0Using Ohm\'s law, V = I\xa0RW = I2\xa0Rt\xa0This work done in carrying the charge th\xa0rough the wire appears as the heat produced. i.e.,H = V\xa0I\xa0t = I2Rt.this energy is dissipated as heat energy.This relationship is also known as Joule\'s Law of Heating
