Answer 1

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

Joules Law of heating:-

According to joules law of heating.

The heat produced in a conductor is directly proportional to the :-

• Square of the current flowing through conductor.
• Resistance of the conductor.
• Time for which the current flows through it.

The equation for joules law of heating is given by :-

★ $</strong><strong>\boxed</strong><strong>{\sf</strong><strong>\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{ </strong><strong>H</strong><strong> </strong><strong>=</strong><strong> </strong><strong> {</strong><strong>I</strong><strong>}^{2} </strong><strong>RT</strong><strong>}}$

Characteristics of heating element wire :-

1. They have very high resistivity.
2. Their melting and boiling point is high.
3. They don't oxidize readily at high temperatures.
