Candela (cd)
This is the SI unit of luminous intensity of a source of light in a specific direction. The candela is the luminous intensity of a black body of surface area placed at the temperature of freezing platinum and at a presence of 101,325 N/m 2 , in the direction perpendicular to the surface. Candela..

One of the greatest discoveries of the eighteenth century was the discovery of electricity. Think of life today without electricity and you will realize the part electricity plays in our day to day life. Static charges will not heat a toaster or operate an electric fan. Most of the jobs we want ele..
Electric Current
If two charged bodies of different potential are placed one beside the other, the charges will not move from one body to the other. But if the two bodies are connected using a conductor, the flow of charges takes place. Charges will flow as long as there is potential difference between the two bodi..
