Question

state and explain Joule's Law of Heating

Answer 1

hiii,

if a current carrying conductor having resistance (r) gets heated by to passing of current (i) for time (t) and the heat thereby produced be H
joules law states that
H propotional to i^ 2 when r and t are constant
H propotional to r when I and t are constant
H propotional to t when r and I constant

so, combining these laws one gets H = i^2rt/ J
where J has a value of 4. 2 calories in C.G.S ans 1 with no unit in S.I

hope helps
