Swelling. Swelling (edema) is a build-up of water in the tissues. This can be caused by retaining salt and water due to medicines or heart, liver, or kidney failure. It can sometimes be due to poor nutrition, pelvic tumors, or a blockage in the veins or lymph system.
Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance. In some respects, reactance is like an AC counterpart of DC (direct current) resistance.
What youÂ´ll learn in Module 6.1. 1  After studying this section, you should be able to describe: â¢ 2 Inductive Reactance. â¢ 3 The relationship between reactance, frequency and inductance. â¢ 4 Graphical representation of inductive reactance.
