Electric Circuits and their Components - The devices which deliver electricity are called the 'sources'and lamps, electric engines, etc. which consume electricity are called 'loads'. Switches are used to switch the loads on and off whenever necessar..

The devices which deliver electricity are called the 'sources'. Lamps, electric engines, etc. which consume electricity are called loads. Switches are used to switch the loads on and off whenever necessary. Hence, the source, the loads, and the switches are connected t..

A conductor having excess electrons is said to be at a negative or at a lower potential and that having less electrons is said to be at a positive or at a higher potentia..

Production of cathode rays - In 1885, Sir William Crookes carried out a series of investigations into the behaviour of metals heated in a vacuum. The experiment of Crookes and others showed that a heated cathode produced a stream of radiation, which could cause gases at low pressure to glow and whi..

Electric Current - If two charged bodies of different potentials 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 d..

Electricity and Matter - It is important to know the atomic picture of matter. The basic unit of all matter is an 'atom'. Each atom consists of a small core called nucleus which accounts to most of its mass consisting of positively charged protons and neutral neutrons and surrounded by li..

It is important to know the atomic picture of matter. The basic unit of all matter is an 'atom'. Each atom consists of a small core called nucleus which accounts to most of its mass consisting of positively charged protons and neutral neutrons and surrounded by lighter negatively charged part..

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..
