electrical switching device

Application to Switching Circuits - The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out th..

Introduction - In the chapter on current electricity, we had learnt about the flow of charges, conditions to produce the flow and how different materials respond to an external electric field. We had seen how materials are classified as conductors and insulator..

A voltmeter is a device used to measure 'potential difference' and an ammeter is a device used to measure 'current'. Ammeters are connected 'in series' to the components through which the current to be measured flows. Voltmeters are connected in parallel to the components acros..

Numerical 02 - Predict the effect on the electrical properties of a silicon crystal at room temperature (300 K) if every millionth silicon atom is replaced by an atom of indium. Given: concentration of atoms = 5 x 10 2 8 m - 3 ; intrinsic carrier concentration = 1.5 x 10 1 6 m - 3 ; intri..

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 loa..

When the electrical appliance is switched on, the metal casing of the appliance will remain at zero potential as it is in contact with the earth wire in the three pin socket. It thus prevents us from an electric shock even if we touch it accidentall..
