where C^, the reading of ^j,is the diagonal of the parallelogram formed hy O (/ and Op, representing the read-ings of A„ and A^, re-spectively. These linescan all be laid off toscale, so many amperesper inch, and the anglesof phase difference read-ily determined. In thiscase ^ is the phase… … Pig. 1442. t c. P Q Fig. 144.3. phase, nop and Oq were in phase, they could be addedtogether directly, and the resultant would be O r, as shownin Fig. 1443. Here the angle of lag has become zero, andthe parallelogram has been reduced to a straight line. 3858. A practical example of the addition of…
