application to switching circuits

>The earth wire is much thicker in size and is made of copper. One end of it is connected to a copper plate buried deep under the earth. The earth connection is made to the electric meter and then to the main switch. In our homes, we receive supply of electric power through a main supply ..

A photocell converts the change in the intensity of light into a change in the electric current. The diagram shows a photocell circuit. The cathode is made of photosensitive materia..

Practical Applications of Joule's Heating - This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. ..

. An 'electric fuse' is an important application of the heating effect of current. When the current drawn in a domestic electric circuit increases beyond a certain value, the fuse wire gets over heated, melts and breaks the circuit. This prevents fire and damage to var..

In this chapter, we have learnt the axioms of Boolean algebra. Also, we have learnt about Boolean expressions, their properties and their applications to switching circuits, in particul..

In this chapter, we have learnt the axioms of Boolean algebra. Also, we have learnt about Boolean expressions, their properties and their applications to switching circuits, in particular...

. Boolean algebra is used in many spheres of activities such as electrical and telecommunication engineering, analysis of propositions, controlling the flow of pulses, mathematical expressions. Therefore, Boolean algebra is considered to be modern mathematics. Before we learn the fundamentals of Bo..
