Question

what is juole's heating effect? write a mathematical expression for juole's law of heating. list its 2 applications in daily life.​

Answer 1

Answer:

Answer: H square is equal to I square into R into T. This is called joule's law of heating. The devices which works on this principle are Electric Heater, Immersion water Heater, Electric bulb,Fuse wire etc.

I hope it's hellpfull

Plz follow me okkkk

Answer 2

If there is a conductor whose resistance is R, current I is flowing through it for time t, then the heat produced is directly proportional to the square of current, resistance and time taken. This is called joule’s law of heating.
H=I^2Rt
Electric heater/ Water heater and Electric fuse are two of its applications.
