Answer 2

Answer:

$<I>$★ When an electric current is passed through an conductor , heat is produced in it . This is known as heating effect of current .

♠ JOULE'S LAW OF HEATING

→ It states that heat is produced in conductor is directly proportional to the

i. Square of current through it

ii. Proportional to its resistance

iii. Time for which current is passed

iv. Mathematically expressed as

H = V×I×t

= VIt / 4.18
