herefore each vrirecuts 20x1,000,000 equals 20,000,000 lines per second. Since it requires cutting at the rate of 100,000,000 persecond to produce one volt, each vrire on the armature pro-duces 20,000,000 equals 1-5 100,000,000 of a volt in passing through the upper air garp. The samewire produces… … Figure 47 Production of E. M. F. in an armature illustrated by two groups of batteries placed in parallel. 115 In Fig. 47 if each cell produces two volts, the whole 12cells produce only 12 volts, but the capacity for deliveringcurrent is doubled. The same thing is true of the dynamoarmature. There…
