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
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 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
Measurement of Power Factor in 3 Phase Load by 2 Wattmeter Method – Electrical Practical
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
To Determine the Efficiency and Voltage Regulation of a Single Phase Transformer by Load Test – Electrical Practical
A single-phase transformer is a type of power transformer that utilizes single-phase alternating current, meaning the transformer relies on a voltage cycle that operates in a unified time phase. They are often used to step-down long distance and localized transmission
To Verify Thévenin’s Theorem – Electrical Practical
Thévenin’s Theorem states that it is possible to simplify any linear circuit, no matter how complex, to an equivalent circuit with just a single voltage source and series resistance connected to a load. In this electrical practical, we will verify
Verification of Principle of Superposition Theorem – Electrical Practical
Superposition Theorem states that a circuit can be analysed with only one source of power at a time, the corresponding component voltages and currents algebraically added to find out what they’ll do with all power sources in effect. To negate all
