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. Kilowatt - hour is the commercial unit of electrica..

Before all the branches of science were clubbed together under the nomenclature 'Natural philosophy', under which all observations of subjective nature were being carried out and spirit of enquiry was almost non-existent, we were satisfied with simple explanations. Before all the branches of..

Everything that we use in our daily life is ultimately governed by principles of physics. All gadgets we use everyday at home, bicycles and cars, all different types of machinery and instruments, work on principles of physics. Hence to understand even the elementary working of these things, t..

Random errors occur in all measurements. They arise when observers estimate the last figure of the reading on an instrument. These include the noise in the room or the mechanical vibrations in the room. These are called random, because they cannot be predicted. The best way of minim..
