Question

state joules law of heating and define
​

Answer 1

Answer:

Joule’s law of heating states that,

when a current ‘i ' passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.

Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat.

Answer 2

Answer:

Joules law of heating states that heat produced in a resistor is directly proportional to

(I) the square of the current

(ii)the resistance

(iii)the time taken

Explanation:

Heat produced =VI t

wkt V=IR

replace this in above eqn

H=IR I t

H=I sq Rt
