Television

  Television Television, often abbreviated as TV, is a device used for transmitting and receiving television signals. It is a popular form of entertainment and a primary source of information for many people around the world. The first electronic television was invented in the 1920s, and over the years, television technology has advanced significantly. Today, televisions come in a variety of sizes and types, including LCD, LED, OLED, and plasma screens. Television broadcasting has also evolved over time, with the advent of cable and satellite TV providing viewers with access to hundreds of channels. In addition to traditional broadcasting, streaming services like Netflix, Hulu, and Amazon Prime have also become popular, allowing viewers to watch TV shows and movies on demand. Television programming includes a wide range of genres, including news, sports, drama, comedy, reality shows, and documentaries. Many TV shows have become cultural icons and have played a significant role in shapi

  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 motor is

  Potential Transformer Potential Transformer: A potential transformer (PT) is a type of instrument transformer used to step down high voltage signals to a lower voltage that can be measured by a meter or other instrumentation. Physical Therapy: Physical therapy (PT) is a type of healthcare that focuses on the prevention and treatment of injuries and disabilities through exercises, manual therapy, and other interventions. Pacific Time: Pacific Time (PT) is a time zone that is eight hours behind Coordinated Universal Time (UTC-8) and is used in parts of North America, including the western United States and Canada. Part-Time: PT can also be an abbreviation for part-time, indicating that someone works fewer hours than a full-time employee. Prothrombin Time: Prothrombin time (PT) is a laboratory test that measures the time it takes for blood to clot. It is commonly used to monitor the effectiveness of blood-thinning medications such as warfari

  Current transformer (CT) A current transformer (CT) is a type of transformer that is used to measure the electric current in a circuit. It works by measuring the current in a primary winding and producing a proportional current in a secondary winding, which can be used to measure the current in the circuit. Current transformers are commonly used in electrical power systems to measure the current flowing through high-voltage transmission lines or in electrical distribution systems to measure the current flowing through individual circuits. They are also used in electrical metering applications to measure the power usage of individual customers. Current transformers are designed to be highly accurate and reliable, and they are typically used in conjunction with other electrical measurement and control devices to ensure the safe and efficient operation of electrical power systems.

Integrated Circuit IC stands for Integrated Circuit, which is a miniature electronic circuit that is made up of multiple components such as resistors, capacitors, transistors, and diodes that are etched onto a small piece of semiconductor material (usually silicon). The components are interconnected by thin metal wires and the entire circuit is encapsulated in a small package made of plastic, ceramic, or metal. ICs were first developed in the 1960s and have since become a fundamental building block of modern electronics. They offer several advantages over traditional circuits built using individual components such as smaller size, lower power consumption, greater reliability, and lower cost. ICs are used in a wide range of electronic devices such as computers, smartphones, televisions, and many other consumer electronics products. There are many different types of ICs that are designed for specific applications such as analog circuits, digital circuits,  microprocessors, memory chips,
