il wound on a given spool is proportionalto the square of the number of turns N of wire. For example, agiven spool wound with No. 16 wire has 500 turns and an induc-tance of, say, 0.0025 henry; the same spool wound with No. 28wire would have about eight times as many turns, and its induc-tance… … ALTERNATING-CURRENT MACHINERY 29 The inductance of a coil of given shape is proportional to itslinear dimensions, the number of turns of wire being unchanged.For example, a given coil has an inductance of 0.022 henry; and acoil three times as large in length, diameter, etc., but having the…
