Question

state joules law of heating and write it's mathematical form??..... ​

Answer 1

Answer:-

The Joules law states that

• The heat produce in a resistor is directly proportional to the square of a current for a given resistance . It means that I² is directly proportional to H.

• The heat produce in a resistor is directly proportional to the resistance of given current . It means that R is directly proportional to R.

• The heat produce in a resistor is directly proportional to the time which the current flows through the resistor.It means that t is directly proportional to H.

Mathematical term of Joules law of heating .

→ H = I²Rt

here

H is the heat produce

I is the current flows

R is the resistance

t is the time taken.

Let's Explore the Ohm's Law

The Ohm's Law state that the potential difference across the end of a metallic wire in an electric current is directly proportional to the current flowing through it .

Mathematical term

→ V = IR

Here

V is the potential difference

I is the electric current

R is the resistance .

Answer 2

Joule's law or heating effect of electric current states that heat produced in a conductor is directly proportional to the

• Square of current flowing through the conductor

• Resistance of the conductor

• Time

Mathematically ,

$\tt \implies H \propto {(I)}^{2} RT$

$\tt \implies H = k {(I)}^{2} RT$

Where , k = constant = 1

$\tt \implies H = {(I)}^{2} RT$
