Electricity and magnetism for advanced students (1920)
Starling, Sydney George, 1873- · London Longmans, Green · leaf 365
The cixrrent is here in advance of the electromotive force by thedifference in phase, $ = tan~ p~T7 The vector diagram is given in Fig. 328 (i) and the electromotive Iforce and current curves for one cycle in Fig. 328 (ii). The power … absorbed in the circuit is again ^IqEq cos 6, and the idle or wattlesscomponent of the current is l„ sin 0 (see p. 350). If in addition, R = 0, tlien 0 = 90^, and the current is entirelywattless. xn. CHOKING COIL \J (iv) When I>i = C^ ^ = then, 1 = Ti- sin pt 355 = 0. In this case the current is…
