Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Inductive Reactance is defined as the opposition to current flow. It is the reaction of the inductor to the changing value of alternating current. To explain further, a back electromotive force (emf) ...

One of the fundamental components of electrical circuits is the inductor, which provides inductance (opposition to changes in electric current). Conventional inductors consist of a coil of wire ...

Mobile-phone chargers and other devices could become much smaller after an all-RIKEN team of physicists successfully shrunk an electrical component known as an inductor to microscale dimensions using ...

Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...

IT was originally supposed that separating contacts in low-voltage, low-inductance circuits interrupted the current without arcing provided the supply voltage was lower than the ionization potential ...
