  Star-Delta connection   Star-Delta connection is a type of three-phase electrical connection used in power transmission and distribution systems. It involves connecting the windings of a three-phase motor or transformer in two different configurations - the star (Y) configuration and the delta (Δ) configuration. In the star configuration, the three windings of the motor or transformer are connected together at a central point, known as the neutral point. Each winding is also connected to one of the three phases of the power supply. In the delta configuration, each winding of the motor or transformer is connected in a loop, with one end connected to the start of the next winding and the other end connected to the end of the previous winding. The star-delta connection allows a motor or transformer to be started with reduced voltage, which can be useful in applications where a high starting current could damage the motor or cause a power outage. During the starting period, the ...

 Transformer      A transformer is a passive electrical device that is used to transfer electrical energy between two or more circuits through the process of electromagnetic induction. It consists of two coils of wire, known as the primary and secondary windings, wrapped around a common magnetic core. When an alternating current (AC) voltage is applied to the primary winding, it creates a magnetic field that induces a voltage in the secondary winding. Transformers are commonly used in power distribution systems to step up or step down the voltage of an alternating current. In step-up transformers, the voltage is increased on the secondary side, which allows power to be transmitted over long distances with less loss due to resistance. In step-down transformers, the voltage is decreased on the secondary side, which is used in power supplies to reduce the voltage from the power source to a level suitable for use in electronic devices. Transformers are also used in audi...

  LED An LED (Light Emitting Diode) is a type of semiconductor device that emits light when an electric current is passed through it. LEDs are made from a special type of semiconductor material that emits light when electrons move through it. The emitted light is typically monochromatic, meaning it has a specific color determined by the materials used to make the LED. LEDs are commonly used as indicators in electronic devices such as computers, televisions, and other consumer electronics products. They are also used as sources of light in a wide range of applications, including automotive lighting, streetlights, signage, and home and commercial lighting. LEDs are popular for their low power consumption, long life, and high efficiency compared to traditional incandescent and fluorescent bulbs.

Relay A relay is an electrical component that is used to control the flow of current in a circuit by opening or closing a switch. In sports, a relay race is a track and field event in which athletes take turns running a set distance before passing a baton to their teammate. In telecommunications, a relay is a device that receives and retransmits signals, typically used to extend the range of a signal. In general, the term "relay" can also refer to the act of passing something on or transferring it to someone else. For example, you might "relay" a message from one person to another. In computing, a relay can refer to a network device that forwards data packets between networks. A "relay" can also refer to a mechanism for controlling a high-powered device, such as a motor, using a low-powered signal. There may be other meanings of "relay" depending on the context, but these are some of the most common ones.

resistor   A resistor is an electronic component that is used to limit or control the flow of electric current in a circuit. It is a passive component, which means that it does not generate or amplify electrical signals, but rather opposes the flow of current. The basic function of a resistor is to provide a specific amount of resistance to the flow of current. The resistance of a resistor is measured in ohms (Ω) and is represented by a color code on the body of the resistor. Resistors can be made from a variety of materials, including carbon, metal film, and wire-wound materials. The most common type of resistor is the carbon composition resistor, which is made by mixing carbon and ceramic materials. Resistors are used in a wide variety of electronic circuits for various applications, such as voltage dividers, current limiting, biasing circuits, and signal conditioning.

  SCR (Silicon Controlled Rectifier) An SCR (Silicon Controlled Rectifier) is a four-layer semiconductor device that acts as a switch, used for controlling high-power circuits in various electronic applications. The SCR can be turned on by applying a small voltage to its gate terminal, which allows a larger current to flow through the device. Once the SCR is turned on, it remains to conduct even after the gate voltage is removed, until the current flowing through it drops below a certain level. The basic structure of an SCR consists of four layers of alternating p-type and n-type semiconductor materials. The gate terminal is connected to the middle layer of the SCR, which acts as a control electrode. The anode (positive terminal) is connected to one end of the SCR, and the cathode (negative terminal) is connected to the other end. When a voltage is applied across the anode and cathode, no current flows through the SCR, as it is in a non-conducting or blocking state. However, when ...

  diode A diode is an electronic component that allows current to flow in only one direction. It is a two-terminal device that has a cathode (negative) and an anode (positive) terminal. When a voltage is applied across the diode in the forward direction, current flows through the diode, but in the reverse direction, the diode blocks the current. The basic operation of a diode is based on the properties of a semiconductor material. A semiconductor material is a material that has an electrical conductivity between that of a conductor (such as copper) and an insulator (such as rubber). When a semiconductor material is doped with impurities, it becomes either an n-type semiconductor (which has excess electrons) or a p-type semiconductor (which has holes or lacks of electrons). A diode is made by joining a p-type semiconductor with an n-type semiconductor, which is called a p-n junction. The p-n junction acts as a one-way valve for the flow of current. When a positive voltage is applie...
