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 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 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
Diode Application in Clamper Circuit (Positive and Negative) – Electronics Practical
A clamping circuit is used to place either the positive or negative peak of a signal at a desired level. The DC component is simply added or subtracted to/from the input signal. The clamper is also referred to as an IC
To obtain V-I characteristics of PN Junction Diode – Electronics Practical
When P and N semiconductors are joined to make the PN junction semiconductor diode, the electrons near the PN junction jump from N to P and holes near the junction jump from P to N. This phenomenon creates a depletion
To study the Diode Applications of Half wave and Full wave Rectifier – Electronics Practical
A rectifier is an electrical device composed of one or more diodes that converts alternating current (AC) to direct current (DC). The process of AC to DC conversion is called rectification. There are two types of single wave rectifiers half
To Study Positive and Negative Clipper (Diode application in Clipper circuit) – Electronics Practical
Clippers or (clipping circuits) are used to prevent the output of a circuit from exceeding a predetermined voltage level without distorting and protecting the circuit from high voltage spikes. The types of clipping circuits (or clippers) are negative clipping circuit and
To obtain V-I characteristics of Zener Diode with Graph – Electronics Practical
Zener diodes are a special type of semiconductor diode– devices that allow current to flow in one direction only –that also allow current to flow in the opposite direction, but only when exposed to enough voltage. We will learn about
To perform Open and Short Circuit test of a Single phase transformer – Electrical Practical
Single-phase transformers accept single-phase AC power and output single-phase AC power, typically at a higher or lower voltage level. Energy is transferred from one circuit to one or more circuits via electromagnetic induction. Open-circuit voltage is the difference of electrical potential
Speed control of a DC shunt Motor by Field Control Method – Electrical Practical
Shunt DC Motors operate on direct current. As such, the field windings and armature are connected in a parallel combination, and in electrical terminology a parallel combination is known as a shunt. This type of motor is a “shunt-wound” DC
