WebInductive Reactance. Inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it and is similar to the opposition to direct current (DC) in a resistance. Thus far we have looked at the behaviour of inductors connected to DC supplies and hopefully by now we know that when a DC voltage ...

WebBasic Electronics - Inductance. The property of an inductor to get the voltage induced by the change of current flow, is defined as Inductance. Inductance is the ratio of voltage to the rate of change of current. The rate of change of current produces change in the magnetic field, which induces an EMF in opposite direction to the voltage source. darwin comes to africaWebIf power is a constant, then, yes, current and voltage are inversely proportional since power is their product.
