turns I^T^ is equal to the effect of the no-loadampere-turns I^T^. The vector IJ^ in the diagram is the resultant of thevectors J^Tj and I^T^. If the no-load ampere-turns I^^T^ are very small compared with theampere-turns when loaded, l-JT-^^ is approximately equal to 1.^7^. This is also true in… … Fig. 268 an adjustable resistance R^. When the secondary circuit is open, the pri-mary winding acts as a choking coil, but if the number of primary turns issmall, the potential drop will be small compared with the terminal p.d. ofthe alternator; it will, however, have its maximum value under this…
