An inverter is a power electronics device used to convert DC voltage into AC voltage. This process must be efficient as this conversion from DC to AC happens frequently in an electrical network. Learn more about Power Inverters in our latest article 🤓 – electrical4u.com/power-inver…

A high pass filter is an electronic filter that permits signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than that cutoff frequency. Learn more about High Pass Filters in our latest post 🤓– electrical4u.com/high-pass-f…

A Klystron (or Klystron Tube) is a vacuum tube that is used to oscillate and amplify microwave frequency signals. It was invented by American electrical engineers Russell & Sigurd Varian. Learn more about Klystron Tubes in our latest article 🤓 – electrical4u.com/klystron-tu…

An Avalanche Diode is a type of semiconductor diode which is designed to experience avalanche breakdown at a specified reverse bias voltage. Learn more about Avalanche Diodes in our latest article 🤓 – electrical4u.com/avalanche-d…

A band pass filter (also known as a BPF or passband filter) is a device that allows frequencies within a specific frequency range and rejects (attenuates) frequencies outside that range. Learn more about Band Pass Filters in our latest article 🤓 – electrical4u.com/band-pass-f…

Harmonics are an unwanted higher frequencies component that is an integer multiple of the fundamental frequency. Harmonics create distortion in the fundamental waveform. Learn more about Harmonics & Fundamental Frequency in our latest article 🤓 – electrical4u.com/fundamental…

Fiber optic cables are network cables that contain many strands of fine glass fibers known as optical fibers. Signals are transmitted through these cables by firing pulses of light through these optical fibers. Learn more about Fiber Optic Cables 🤓 – electrical4u.com/guidance-to…

The NPN transistor is the most commonly used bipolar junction transistor, and is constructed by sandwiching a P-type semiconductor between two N-type semiconductors. Learn more about NPN transistors in our latest article 🤓 – electrical4u.com/npn-transis…

A PNP transistor is a bipolar junction transistor constructed by sandwiching an N-type semiconductor between 2 P-type semiconductors. A PNP transistor has 3 terminals – a Collector, Emitter & Base. Learn more about PNP transistors in our latest post 🤓 – electrical4u.com/pnp-transis…

The transmittance of a surface or material is the part of the light that moves through to the other side of the surface. When light passes through any material it can be transmitted, reflected, or absorbed. Learn more about transmittance 🤓 – electrical4u.com/what-is-tra…

Reflectance is defined as the ratio of the radiant flux reflected from the surface, body, material, to the incident radiant flux. Reflectance is denoted by ρ. There is both Specular Reflectance or Diffuse Reflectance. Learn more about Reflectance 🤓 – electrical4u.com/what-is-ref…

A Rogowski coil is an electrical device that is used to measure alternating current (AC). It is also used to measure the high-speed transient, pulsed current or sinusoidal current. Learn more about Rogowski Coils in our latest article 🤓 – electrical4u.com/rogowski-co…

Reactance is defined as the opposition to the flow of current from the circuit element due to its inductance and capacitance. Learn more about Reactance in our latest article 🤓 – electrical4u.com/electrical-…

Electromagnetic interference (EMI) is a disruption that affects an electrical circuit because of either electromagnetic induction or externally emitted electromagnetic radiation. Learn more about EMI in our latest article 🤓 – electrical4u.com/electromagn…

Photometry is the science of the measurement of the visible range light, in terms of its brightness to the human eye. Photometry only relates to the visible range of wavelength (light). Learn more about Photometry in our latest article 🤓 – electrical4u.com/photometry/

DC stands for Direct Current. Direct current is a unidirectional flow of electric charge. The electrons move from an area of negative charge to an area of positive charge without changing direction. Learn more about Direct Current in our latest post 🤓 – electrical4u.com/dc-current/

A slip ring is an electromechanical device used to connect a stationary system to a rotating system. It is used in applications that require rotation while transmitting power or electrical signals. Learn more about Slip Rings in our latest article 🤓 – electrical4u.com/slip-ring/

Conductance is the potential for a substance to conduct electricity. Conductance is the measure of how easily electrical current (i.e. flow of charge) can pass through a material. Learn more about Conductance in our latest article 🤓 – electrical4u.com/conductance…

A Darlington transistor is an electronics component made via the combination of two Bipolar Junction Transistors connected in such a way that it allows a very high amount of current gain. Learn more about Darlington Transistors in our latest article 🤓 – electrical4u.com/darlington-…
