electric unit conversion

Current Electricity - 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 to..

Commercial Unit of Electrical Energy - The unit 'watt' is very small. Therefore, in actual practice we use a much larger unit called 'kilowatt'. It is equal to 1000 watts. Since electrical energy is the product of power and time, watt hour (W h) can..

Kilowatt - hour is the commercial unit of electrical energy. We have seen that power is the rate of energy consumed or delivered. If 1 joule of energy is used per second, we say that energy is used at the rate of 1 watt. In other words, if energy is used at the rate of 1 watt, t..

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 ch..

Electric Power - Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric ..

Electric Circuits - Your everyday experiences have familiarised you with many electric circuits. Let us take an example of an electric circuit with a battery (a source of electricity), toaster and a switc..

Electric Field - The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that point. If is the electrostatic force experienced by a test charge q at a point, then the electric field intensity a..

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 surrou..

A current is any motion of charge from one region to another. The illustration below shows two bodies at different potentials. When these are connected with a wire, free electrons flow from B to A until both bodies attain the same potential, after which the current ceases to flow. Current flows if ..
