A spectral line is like a fingerprint that can be used to identify the atoms, elements or molecules. It is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. We will show you how to determine the variation of magnetic field along axis of current carrying
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. We will study the input and
The junction gate field-effect transistor, or JFET, is the simplest type of field-effect transistor. In a junction field-effect transistor, or JFET, the controlled current passes from source to drain, or from drain to source as the case may be. The controlling
In this practical we will identify the various electronic components such as LED, resistor, capacitor, CRO etc. with their specifications. Practical Images Watch this Video to know more about basic Electronic components Thanks for viewing our post, hope you liked it and
In two wattmeter method, we have two types of connections: Star connection of loads Delta connection of loads. In star connection of load, the reading of wattmeter one is product phase current and voltage difference (V2-V3) and the reading of wattmeter
An electric motor is an electrical machine that converts electrical energy into mechanical energy. In case of three phase AC operation, most widely used motor is Three phase induction motor as this type of motor does not require any starting
