The Seebeck effect is a phenomenon in which a voltage is generated between the ends of a conductor when the temperature at one end is different from the temperature at the other end. It is named after the German physicist Thomas Johann Seebeck, who first described it in the early 19th century. Defin

Moore’s Law is a prediction made by Gordon Moore, co-founder of the technology company Intel, in 1965 that the number of transistors on a microchip would double approximately every two years. This prediction has proven to be remarkably accurate, and has served as a driving force in the rapid develop

What is meant by Electronic Ballast? An electronic ballast, also referred to as an electrical ballast, is a component of equipment that controls the starting voltage currents of the lighting fixtures. This is accomplished by the use of the electrical gas discharge technique. To start the gas dischar

For the purpose of accurately representing a specific electrical system or circuit in Electrical and Electronics Engineering, many forms of drawings and diagrams are used. These electrical circuits are shown using lines, which stand in for wires, and symbols or icons, which are used to represent the

The method of connecting non-current carrying portions to earth or ground, such as the metallic frame of an electrical device or certain electrical components of a power system, such as the neutral point of star-connected system, is known as grounding, also referred to as earthing. To avoid accident

Fleming’s Left-Hand Rule is a principle in electromagnetism that describes the relationship between the direction of the current in a conductor, the direction of the magnetic field around the conductor, and the direction of the force on the conductor. It is similar to Fleming’s Right-Hand Rule, but

Fleming’s Right-Hand Rule is a principle in electromagnetism that describes the relationship between the direction of the current in a conductor, the direction of the magnetic field around the conductor, and the direction of the force on the conductor. Fleming’s Right-Hand Rule states that if the th

The Delta-Star transformation is a technique in electrical engineering that allows the impedance of a three-phase electrical circuit to be transformed from a “delta” configuration to a “star” (also known as “Y”) configuration, or vice versa. The delta configuration is a circuit in which the three ph

The Star-Delta transformation is a technique in electrical engineering that allows the impedance of a three-phase electrical circuit to be transformed from a “delta” configuration to a “star” (also known as “Y”) configuration, or vice versa. The delta configuration is a circuit in which the three ph

In electrical engineering, the Maximum Power Transfer Theorem states that in a passive, two-port, linear network, the power transmitted to the load is maximised when the load resistance (R L ) is equal to the Thevenin equivalent resistance (R TH ) of the network. The Thevenin equivalent resistance o

The Compensation Theorem is a principle in electrical engineering that allows the response of a linear, two-port network to be determined based on the response of the network to a single input. It states that the response of a two-port network to any two inputs can be determined by measuring the res

The Reciprocity Theorem is a principle in electromagnetics that relates the voltage and current at two points in a linear, passive network. It states that the ratio of the voltage at one point to the current at another point is equal to the ratio of the current at the first point to the voltage at t
