It is an inductor designed to block (have ahigh reactance to) higher frequencies in anelectrical circuit while passing signals ofmuch lower frequency or direct current.They are inductances thatisolate AC frequency currents from certainareas of a radio circuit. They can be used to

block alternating current whilepassing direct current.

WilliamOughtred and others developed the X in the 17th century

based on the emerging work on logarithms by John Napier.Before the advent of the pocket calculator, it was the mostcommonly used calculation tool in science and engineering. Theuse ofX continued to grow through the 1950s and 1960s evenas digital computing devices were being gradually introduced;

but around 1974 the electronic scientific calculator made itlargely obsolete.In its most basic form, the X uses two logarithmic scales to allowrapid multiplication and division of numbers. These commonoperations can be time-consuming and error-prone when doneon paper. More elaborate X allow other calculations, suchas square roots, exponentials, logarithms, and trigonometricfunctions.X is of two words. X?
