This phase angle of reactive opposition to current becomes critically important in circuit analysis, especially for complex AC circuits where reactance and resistance interact.

Does inductance depend on current, frequency, or both?

Inductive Reactance Formula & Calculations

Any conductor, in which the current is changing, will produce a changing magnetic field around it. This results in a voltage wave that is 90 o out of phase with the current wave.

Last Modified Date: What minimum inductance should it have to produce a reactance for 15. A radian is a unit of angular measurement: Thus high frequencies are impeded the most. So the back emf generated at switch off is more than 4 times higher than the supply voltage! This article will try to develop a better insight into wave reflection that can occur when driving a relatively long wire with a fast logic...

AC Inductor Circuits

These high voltage pulses that occur when an inductive component such as a motor or relay coil is switched off, can potentially cause damage to the output transistor or integrated circuit switching the device.

Learn about Electronics - AC Theory. Back to CTT. Phase and Phasors 6. Because inductance in henries depends on so many variable quantities, it is quite difficult to calculate accurately; numerous formulae have been developed to take different design features into account.

This is because the voltage is continually reversing, charging and discharging the capacitor. Remember, the voltage dropped across an inductor is a reaction against the change in current through it.

Inductors and Inductive Reactance Suppose an inductor is connected directly to an AC voltage source, as shown in [link]. At point a, the capacitor has fully discharged on it and the voltage across it is zero. The graph in [link] b starts with voltage at a maximum. It can be seen from the diagram that the two quantities need to be added together vectorially.

Module 3.2

A miniature inductor is wound on a plastic former, into which a ferrite iron dust core is screwed sufficiently to provide a core giving the right amount of inductance. When the voltage becomes negative at point a, the current begins to decrease; it becomes zero at point b, where voltage is its most negative.
