Electrical4U

Rogowski Coil: What is it & How Does it Work? (Current Sensor) | Electrical4U

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 🤓 – https://www.electrical4u.com/rogowski-coil/ #electrical4u #electricalengineering #electronics #engineering

Electrical Reactance: What is it? (Inductive & Capacitive) | Electrical4U

Reactance is defined as the opposition to the flow of current from the circuit element due to its inductance and capacitance. The reactance is inductive if it releases energy in the form of a magnetic field. And the reactance is capacitive if it releases energy in the form of an electric field.

Electromagnetic Interference (EMI): What it is & How To Reduce it | Electrical4U

Electromagnetic interference (EMI) is a disruption that affects an electrical circuit because of either electromagnetic induction or externally emitted electromagnetic radiation. EMI is the interference from one electrical or electronic system to another caused by the electromagnetic fields generated by its operation.

Photometry: What is it? (Fibre, Flame & Reflectance Photometry) | Electrical4U

Photometry is the science of the measurement of the visible range light, in terms of its brightness to the human eye. Photometry is distinct from radiometry, which is the science of measurement of radiant energy (including light) in terms of absolute power. Photometry only relates to the visible range of wavelength (light).

Slip Ring: What is it? (And How Does it Work?) | Electrical4U

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 🤓 – https://www.electrical4u.com/slip-ring/ #electrical4u #electricalengineering #electronics #engineering #motors

Conductance: What is it? (Definition, Units & Formula) | Electrical4U

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. Conductance is the inverse (or reciprocal) of electrical resistance, represented as 1/R.

Impedance Matching: Formula, Circuit & Applications | Electrical4U

Impedance matching is the process of designing the input impedance and output impedance of an electrical load to minimize the signal reflection or maximize the power transfer of the load.

Load Factor: What is it? (And How To Calculate It) | Electrical4U

Load Factor is defined as a ratio of the average load divided by the maximum (or peak) load in a given time of period. Learn more about Load Factor in our latest article 🤓 – https://www.electrical4u.com/load-factor/ #electrical4u #electricalengineering #electronics #engineering #power

Fresnel Equations: What are they? (Derivation & Explanation) | Electrical4U

The Fresnel Equations are the ratio of the electric field of a reflected and transmitted wave to the electric field of the incident wave.

Admittance: What is it? (Formula & Admittance vs Impedance) | Electrical4U

Admittance is a measure of how easily a circuit or device will allow current to flow through it. Admittance is the reciprocal (inverse) of impedance akin to how conductance and resistance are related.

Magnetic Reluctance: What is it? (Formula, Units & Applications) | Electrical4U

Magnetic reluctance is the opposition offered by a magnetic circuit to the production of magnetic flux. It is the property of the material that opposes the creation of magnetic flux in a magnetic circuit.

Radiometry: What is it? (Microwave & Photothermal) | Electrical4U

Radiometry is a technique to measure electromagnetic radiation for any wavelength. It is similar to photometry, but photometry is related to visible light signals only, while radiometry includes signals of any wavelength.
