Almost all electrical energy is generated, transmitted, and distributed in the form of alternating current (AC). The power factor plays an important role in the AC system since the power consumed depends upon this factor. The load on the power system is inductive (e.g. induction motors, arc...
Electric Current Units: The SI unit for current is the ampere (A), representing 1 coulomb of charge passing a point in 1 second. AC vs DC Current: Alternating current (AC) periodically reverses direction, while direct current (DC) flows in one direction. Current Measurement: Current is measu...
•Alternating Current (AC): Here, electrons oscillate back and forth ("wiggle," in a sense) very rapidly. This type of current is often easier to generate in a power plant, and it also results in less energy loss over a large distance, which is why it is the standard used t...
On the basis of the flow of electric charge, the current can be classified into two types, which arealternating currentand direct current. In direct current, the charges flow in one direction but in alternating current, the charges flow in both the direction. The Formula for Electric Current...

Reactance is the property of an electrical component to oppose the change in current while impedance is the combination of resistance and reactance. There are two types of reactance: Capacitive & Inductive
Cole-Cole formulaThe dependences of the alternating current magnetic susceptibilities of nanocomposite rare-earth titanates on the magnetic field are investigated. The nanocomposites are prepared in opal matrices with rare-earth titanate particles having a pyrochlore structure. The measurements are performed...

Current density in a conductor can be defined as the charge flow through any cross-section of theconductor. However, the current density alters in different parts of an electrical conductor resulting in alternating currents at higher frequencies. Electric current always creates amagnetic field. With ...
