Question

Explain conservation and quantization of charge

Answer 1

In physics, charge conservation is the principle that electric charge can neither be created nor destroyed. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved. ... Let's talk about electrons and quantization of electric charge.

Explain conservation and quantization of charge.

$\rule{200}{4}$

$\bold{\boxed{\large{\boxed{\orange{\small{\boxed{\large{\red{\bold{\:ANSWER}}}}}}}}}}$

$\rule{200}{4}$

$\Large\bold\star\underline{\underline\textbf{Quantisation of charge\:}}$

→ According to quantization of charge,

The charge on a body is equal to an integral

of multiple of basic charge (±e).

i.e. q = ± ne

(where n = 1,2,3,4........................so on.

$\rule{200}{4}$

$\Large\bold\star\underline{\underline\textbf{Conservation of charge\:}}$

→ According to the law of conservation of charge , the algebraic sum of positive and negative charges in an isolated system, remains constant.

$\Large\bold\star\underline{\underline\textbf{Examples\:}}$

» Quantization of charge ,

i.e. q = ±ne

if , n = 1 (we know e = 1.6 x 10^-19 C.

q = ± 1e = ± 1 x 1.6 x 10^-19 C

= ± 1.6 x 10^-19 C.

» Conservation of charge ,

When a glass rod is rubbed with a piece of silk , glass rod acquires positive charge and silk is acquire equal negative charge. Thus , deep isolated system of glass rod and silk piece has zero net charge before and after rubbing.
