Tag: electric current and its effects

Prefix Mega means $ 10^6 $.

Given, P$\displaystyle = 805 W, V= 230 V$
$\displaystyle \therefore =I \frac{P}{V}$
$\displaystyle = \frac{805}{230}= 3.5ampere.$

Electrical Power is defined as the electrical work done per unit time.

According to Joule's heating effect of current, heat energy is generated across a conductor due to the current flowing through it and hence its temperature increases.

Whenever an electric current is passed through a conductor, it gets heated up. And the amount of heat created is directly proportional to the square of the current.

Whenever an electric current is passed through a conductor,it gets heated up. This indicates that a part of electrical energy gets converted into heat energy.

An electric bulb works on the principle of hearing effect of current. It consists of a tungsten filament with a coating of thorium.

he electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself. Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have revolutionized energy-efficient lighting. CFLs are simply miniature versions of full-sized fluorescents.

$1.$ Bulb work by heating up a small wire called a filament. Electric current heats the filament so much that it glows.

ISI mark is a certification mark for industrial products in India. The mark certifies that a product confirms to the Indian Standard(IS), mentioned as CM/L-xxxxxxx on top of the mark, developed by the Bureau of Indian Standards (BIS), the national standards body of India
