xis, while the vector OE^ lies below it. The projection of OE^ istherefore positive and the projection of OE^ negative, and since they opposeeach other, their resultant vanishes. Here again, the directions of thevectors correspond with the geometrical positions of the coils. Such con-siderations as… … Fig. 228 Fig. 229 We can, however, go a step further and substitute effective values of theelectromotive forces instead of maximum values. This will simply alter thescale of the vector diagram without altering the angles. The length OR wiUthen represent the effective value of the resultant. In a…
