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
To verify the Stefan’s law by Electrical method – Physics Practical
Stefan’s law states that the energy radiated per second by unit area of a black body at thermodynamic temperature T is directly proportional to T4. The constant of proportionality is the Stefan constant, equal to 5.670400× 10–8 Wm–2 K–4. This practical will
To determine Band Gap of given semi-conductor material – Physics Practical
Band Gap (or energy gap) is an energy difference which an electron should attain to break free of it’s bounded state. When the band gap energy is met, the electron is excited into a free state, and can therefore participate in
To calibrate Voltmeter with Potentiometer – Physics Practical
We are required to calibrate the Voltmeter to know about its error and adjust it to get near to ideal readings. In this practical we will show you how to calibrate the voltmeter using a Potentiometer. Practical of calibration of Voltmeter using Potentiometer Watch
To determine coefficient of viscosity of water by Poiseuille’s Method – Physics Practical
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. In this practical we will show you how to determine the coefficient of viscosity of water by Poiseulle’s Method. Practical to
To determine Variation of Magnetic Field along Axis of Current Carrying Coil – Physics Practical
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
To find Power and Energy of Periodic and Non-Periodic Functions – Electronics Practical
A signal is a periodic function if it completes a pattern within a measurable time frame, called a period and repeats that pattern over identical subsequent periods. A signal that does not repeats its pattern over a period is called aperiodic function or non
To Study Various kinds of Signal wave forms and Measure their Frequencies – Electronics Practical
The basis of electronics is the electronic signal, an electric current that represents information. There are two basic types of electrical signals: analog and digital. In analog signals, some continuously variable aspect of the electrical current represents the information. In
To study Transistor Input/Output Characteristics in CE, CB, CC Configuration – Electronics Practical
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
To study Transistor Input/Output Characteristics of JFET – Electronics Practical
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
