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
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
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
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
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
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
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
A single phase energy meter is electrical meter used to measure the amount of electrical energy consumed by electrical devices, residences and business. The basic working of Single phase induction type Energy Meter is only focused on two mechanisms: Mechanism
