diagram.Fig. 24; i, ^, 3, and 4 represent the field coils of a four-poledynamo, there being a break in coil 2 at B. The terminals aand e of the field winding are connected to the + and — ter-minals of a live circuit; that is, a circuit connected toa dynamo in operation. It will be seen that… … Fig. 24. therefore, a voltmeter connected to a and b^ as. at F, willshow no deflection. But terminal c of coil 2 is connected to the — side of the circuit;so a voltmeter connectedto b and c, as at F,, willshow a deflection, and, infact, will indicate the dif-ference of potential be-tween a and e.…
