Three phase voltage is the most widely used AC power system in the world. It forms the backbone of electric power generation, transmission, distribution, and industrial applications. Compared to a single-phase supply, a three-phase system delivers higher efficiency, smoother torque, lower conductor cost, and constant power transfer. Because of these advantages, almost all industrial machinery, […]

A rheostat is an important electrical component widely used in power and control circuits. It is mainly used to control current in a circuit without interrupting the supply. Rheostats are commonly found in laboratories, industrial equipment, motor control systems, and high-power applications.   What is a Rheostat? Definition: A rheostat is a type of variable

A carbon composition resistor is one of the oldest and most widely used types of fixed resistors in electrical and electronic circuits. Due to its simple construction, low cost, and wide resistance range, it has been extensively used in early electronic equipment, radios, amplifiers, and general-purpose circuits. Although modern resistors such as carbon film and

Linear Variable Differential Transformer (LVDT) is one of the most popular electromechanical transducers used for precise measurement of linear displacement. It converts small mechanical movement of a soft iron core into a proportional electrical voltage. Because of its high accuracy, reliability and frictionless operation, the LVDT is widely used in industrial control, automation, aerospace, power

Definition of Solar Lamp A solar lamp (or solar light) is a lighting device that uses solar energy instead of grid electricity. During the day, a solar panel converts sunlight into electrical energy and stores it in a rechargeable battery. At night, an electronic controller supplies this stored energy to a high-efficiency LED lamp, providing

Definition A Maximum Power Point Tracking (MPPT) charge controller is an electronic DC–DC converter used in solar power systems to extract the maximum possible power from photovoltaic (PV) panels and deliver it to batteries or DC loads. Unlike simple PWM controllers that switch the panel directly to the battery voltage, MPPT controllers continuously adjust the

Definition A solar inverter is an electronic device that converts the direct current (DC) generated by photovoltaic (PV) solar panels into alternating current (AC) that can be used by household appliances or exported to the electrical grid. Inverters typically also provide protective functions, system monitoring, and sometimes maximum power point tracking (MPPT) to optimize energy

  Definition House wiring (or residential electrical wiring) refers to the set of conductors, protective devices (circuit breakers/fuses), sockets, switches, light fittings and earthing arrangements installed to distribute electricity within a dwelling. Its primary goals are to provide reliable power and protect people and property from electrical hazards through correct circuit design and protection. Key

The short-circuit (SC) test determines the series equivalent impedance of a transformer (as referred to one side, usually the primary). In the test the transformer’s secondary terminals are shorted and a reduced voltage is applied to the primary so that rated (or required) current flows. Measured quantities are the applied voltage VSC, the input current
