What is Wattmeter? The wattmeter is a device that measures the active electric power (or the average rate of flow of electrical energy) of any given circuit in watts. Electromagnetic wattmeters measure utility and audio frequency power; radio frequency measurements require other types. An electrodynamic device is the traditional analog wattmeter. The gadget comprises two …
What is Transducer? A transducer is a device or algorithm that converts energy from one form to another. In electrical engineering, for example, a transducer can convert electrical energy into mechanical energy (such as in a motor) or vice versa (such as in a generator). In computer science, a transducer is an algorithm that processes …

What is Serial Communication? Serial communication is a process in the field of telecommunication and data transmission. Here the data that is subjected to be transmitted goes sequentially, one bit at a time. This whole process happens over a channel of communication or a computer bus. To make it simpler to comprehend, we can take …

What is Open Loop System? Open loop systems are systems where the output is not fed back to the input. These systems are also known as non-feedback systems. The information is not adjusted based on the output in open-loop systems. The output of an open loop system is determined solely by the system’s input and …

What is LVDT? LVDT (Linear Variable Differential Transformer) is a type of sensor used to measure displacement or position. It is a non-contact device, meaning it does not require physical contact between the estimated object and the sensor. It uses an electromagnetic field to measure changes in the position of a conductive core. The core …
What is LED? Light-emitting diode (LED) is a type of diode that is a semiconductor device that converts electrical energy into light energy. LEDs are more efficient than traditional lighting sources, such as incandescent and fluorescent lamps, and can last up to 10 times longer. They are composed of semiconductor materials, such as silicone, doped …
What is Grounding? Grounding connects an electrical system to the earth to ensure that the electrical system has the same potential as the earth and provides a reference point for current flow. It is also precautionary since it protects persons and property from electric shock. The electrical system is usually grounded by connecting it to …
What is Eddy Current? Eddy currents are electric currents induced in conductive materials, such as metals, by a changing magnetic field. A static or time-varying magnetic field, such as an alternating current (AC), may generate a changing magnetic field. Eddy currents are created in a conductor when the magnetic flux through its cross-section changes. Eddy currents …
What is AC Transmission Line? AC transmission lines transfer electrical power from one point to another. These lines are composed of conductors, insulators, and supporting structures. The conductors used in these lines are typically made of aluminum or copper and are mounted on insulated cross-arms or towers. The insulators are glass or porcelain and are …
