JOULES HEATING LAW: –Explanation: – When a current ‘I’ passes through the resistor conductor ‘R’ during the time ‘t’, the square of the heat current generated in the conductor is equal to the generation of resistance and time.H = I ^ 2RtWhere H = HEAT DEVELOPED IN CONDUCTORS, the joule law shows the relationship between the heat generated and the current flowing through a conductor.Applications of Joule’s heating effect:(1) From the heating effect of current, electric iron, electric toaster, electric oven, room heaters, water heater, etc. It is used in the operation of electric heating devices. (2) The heating effect of electric current is utilized in light bulbs. (3) The heating effect of electric current is used in electric fuse to protect household wiring and electric appliances. Solved example of Joule’s heating effect: –EXAMPLE 1:Find the heat energy generated at a 12.2 Ω resistor when a 5.8 A current passes through it for 7 m …
