From our earlier discussions we have understood that electrical resistance of all elements changes in response to the variations in its temperature. Temperature coefficient of resistance is defined as the […]

Several electrical resistances could be hooked up both in series or in parallel, likewise, in excess of 2 resistances may also be joined in groups of series and parallel each. […]

You may come across a number of voltage sources and also current sources in our day to day life. Batteries, DC generator or alternator etc, each one is quite normal […]

In the field of instrumentation we find DC supply being utilized for implementing analog representation of specific physical quantities such as weight, pressure, motion etc. The reason being DC signals […]

Series circuit or series network signifies cases where a pair of or more electric parts are tied up with each other in a string like set up inside a circuit. […]

Voltage drop suggests the decrease in voltage or voltage decline. Because of the existence of the impedance or passive components, you will see certain reduction in voltage as the current […]
