The modern age is an age of electricity. People are so used to electric lights‚ radio‚ televisions‚ and telephones that it is hard to imagine what life would be like without them. When there is a power failure‚ people grope about in flickering candlelight. Cars hesitate in the streets because there are no traffic lights to guide them‚ and food spoils in silent refrigerators. Yet‚ people began to understand how electricity works only a little more than two centuries ago. Nature has apparently

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this

Magnetic effect of electric current is one of the major effects of electric current in use‚ without the applications of which we cannot have motors in the existing world. A current carrying conductor creates a magnetic field around it‚ which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor. The direction of the magnetic field

that Nature is almost Physics (apart from the fact that the word Physics itself is derived from Greek "physis" meaning nature). Physics is all around us. We can find Physics as the backbone for any daily life example such as an electric light‚ electricity‚ the working of our vehicle‚ wristwatch‚ cell phone‚ CD player‚ radio‚ plasma TV set‚ computer‚ and - the list goes on. As we all know physics is the study of natural phenomena. Any sort of technology which we uses in our daily life is related
