Resonance As with series circuits containing resistances, inductances, and capacitances, if the inductive reactance of a parallel circuit equals the capacitive reactance, the circuit is said to be ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Of special value to us is the effective AC circuit resistance at some specific frequency, called inductive reactance, expressed in ohms. Inductive reactance is found by the formula XL=2ΠfL.

The MOSFET power switch is commonly the most vulnerable part of a new switched-mode high-power circuit. One threat for this device is exceeding the value of the maximum allowed pulse current. You ...
