Question

what should be the characteristics of a heating element? what conclusion can be drawn from the relationship H=I^2RT

Answer 1

Answer:

work done = force × displacement.

W=Energy.

energy= N/m^2

energy=Joule.

so

when electron start moving and potential deference are responsible for moving charge in a circuits on that time current get produce but during travelling of charge , charge start collision with resistance of a wire or circuits which produce heat . so workdone= force × displacement but here force applied by potential V and displacement is happen on chargeQ so we form an equation=W=Vq

W=IRIT

W=I^2RT but here workdone cause heat energy so W=H

H=I^2RT.
