PRACTICAL MAKES THEORY PERFECT

That is the way we all of us have learnt even as a child-to talk, walk, ride a cycle,etc.,.Many arts and special skills like dancing, singing swimming, and martial arts are all learnt by going to an expert or a teacher who makes us learn by doing rather than by listeningto lectures or reading books

.Why “learning by doing” is so important? Because, while doing we tend to fail and failures are very important in the learning process. Once we fail we start analyzing what went wrong. Thus at the point of failure a profound learning takes place.

That is why people say:FAILURES ARE STEPPING STONES TO SUCCESS!In order to master the basic principles of electronics one has to study about the different components, circuits And measuring instruments used in electronics. There are two types of components that we come across namely Active and Passive components.

Resistors, Capacitors,etc., are known as passive components because they can only attenuate the electrical voltage and signals And cannot amplify. Whereas deviceslike transistors, operational amplifier(Op Amp) can amplify or increase the amplitude And energy associated with the signals. Hence the transistors and OpAmp come under active devices.

These components can be combined in different configurations by interconnecting them with conducting wires to build different useful Electronic circuits. We would here study about rectifiers, amplifiers, Oscillators, etc., under the category of circuits.

Apart from the components and circuits we must also have familiarity on the principle of operations and usefulness of Some of the essential electronic measuring instruments such as digital multimeters, regulated power supplies, Function generators, oscilloscopes, etc., These help us in trouble shooting the circuits and identify the faulty components Whenever the circuits that we build do not work as expected.
