Question

Distinguish between the term overloading and short circuiting as used in domestic circuits

Answer 1

$\left(a\right)$ Overloading occurs when an electric circuit draws more current than the permitted value and short circuiting occurs when the ends of a circuit are connected by a conductor of very low resistance as compared to that of circuit$.$

$\left(b\right)$ The coils of electric toaster made of an alloy rather than pure metal because$:-$

$\left(1\right)$ resistivity of alloys is generally higher than its constituent metals$.$

$\left(2\right)$ It has high melting point$.$

$\left(3\right)$ It does not oxidise $i.e.,$ burn$.$
