Everything electrical engineering - Transformers, Generators, Batteries, Theory, and more.

AÂ transformerÂ is an electrical deviceÂ that transfers electrical energy from one circuit to another through the process ofÂ electromagnetic induction. It is commonly used to increase or decrease voltage between circuits.

TheÂ work function is the minimum amount of thermodynamic work (i.e. energy) required to remove an electron from a solid to a point in the vacuum immediately outside the solid surface. Learn more about the Work Function in our latest article ð¤ â https://www.electrical4u.com/work-function/ #electrical4u #electricalengineering #electronics #engineering #physics

A resistor is a passive component in a circuit which provides resistance to the flow of current. There are many different types of resistors â learn all about them in this post.Â #Electrical4UÂ #electricalengineeringÂ #resistorsÂ #resistance

QAM (Quadrature Amplitude Modulation) is defined as the modulation technique which is the combination of phase and amplitude modulation of a carrier wave into a single channel. Learn more about QAMs in our latest article ð¤ â https://www.electrical4u.com/quadrature-amplitude-modulation-qam/ #electrical4u #electricalengineering #electronics #engineering #signals

A standing wave ratio meter (SWR meter) is a device that measures the standing wave ratio in a transmission line. The SWR meter measures the degree of mismatch between a transmission line and its load. Learn more about SWR Meters in our latest post ð¤ â https://www.electrical4u.com/swr-meter/ #electrical4u #electricalengineering #electronics #engineering #swrmeter

Cutoff frequency is defined as a boundary in a systemâs frequency response at which energy flowing through the system begins to be attenuated (reflected or reduced) rather than passing through.

A resistor is a passive component in a circuit which provides resistance to the flow of current. There are many different types of resistors â learn all about them in this post.Â #Electrical4UÂ #electricalengineeringÂ #resistorsÂ #resistance

Nominal voltage is a value assigned to a circuit for the purpose of conveniently designating its voltage class. The actual voltage at which the circuit operates may vary from the nominal voltage.

An induction motor is a commonly used AC electric motor. In this motor, the current in the rotor needed is obtained via electromagnetic induction from the rotating magnetic field of the stator winding.

A piezoelectric transducer is a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, temperature or force by converting this energy into an electrical charge. Learn more in our latest post ð¤ â https://www.electrical4u.com/piezoelectric-transducer/

Active & passive components are the 2 main types of electronic elements. Active components supply or amplify energy in an electric circuit, while passive components can only receive energy.
