CHAPTER-3-ELECTRICITY AND CIRCUITS-IIT FOUNDATION-STANDARD VI
We have two types of electricity Static electricity is also known as frictional electricity. When one object is rubbed by another object, heat so produced, get absorbed by electrons over…
What is motion? and explain about measurement of distances-physics-standard VI-IIT Foundation
We see many things moving around us. A boy walking along a road, a man running a race, a boy driving a car, a speeding truck. In all these examples…
Explain about Light, Shadow and Reflection-physics-standard VI-IIT Foundation
LIGHT — A FORM OF ENERGY Light is a form of energy which creates the sensation of vision. Imagine how the world would be if there were no light around…
Explain briefly about NUCLEAR FISSION-physics-standard X-IIT Foundation
NUCLEAR FISSION : In 1939 two German scientists Otto Hahn and Frilz Strassman very carefully analysed the products of their experiments on bombardment of uranium with neutrons. One of the…
Explain Types of Sources of Energy-physics-standard X-IIT Foundation
Energy is the capacity of a body for doing work. Energy stored in a body or system is equivalent to total work done by the body till whole of its…
Explain the working of AC generator, DC generator and Motor-physics-standard X-IIT Foundation
ELECTROMAGNETIC INDUCTION : When an electric current is passed through a conductor, a magnetic field is produced around the conductor. Faraday thought that as a magnetic field is produced by…
Explain about Permanent and Temporary magnets-physics-standard X-IIT Foundation
PERMANENT AND TEMPORARY MAGNETS : The degree to which magnetism is retained by a given piece of iron depends entirely upon its constitution. Steel retains the largest amount while soft…
Explain about Magnetic Effect of Current?-physics-standard X-IIT Foundation
MAGNETIC EFFECT OF CURRENT : Hans Oersted, in 1820, first discovered that when an electric current is passed through a conducting wire, a magnetic field is produced around it. If…
Explain House hold Electrical circuit-physics-standard X-IIT Foundation
HOUSE – HOLD ELECTRICAL CIRCUIT : Electric power is usually generated at placed which are very far from the placed where it is consumed. At the generating station, the electric…
Explain Heating Effect of Power? and Electric Power?-physics-standard X,IIT Foundation
HEATING EFFECT OF CURRENT : When the ends of a conductor are connected to a battery, then free electrons move with drift velocity and electric current flows through the wire.…
