1. A4 pole, de generator has a wave wound armature with 792 conductors. The flux per pole is 0.0121Wb. Determine the speed at which it should run to generate 240 V at no load. 2. A de generator when driven at 1000 r.p.m. with a flux per pole of 0.02 Wb, produces an e.m.f. of 200V.If the speed is increased to 1 100 r.p.m. and the flux per pole is reduced to 0.019 Wb per pole what will be the new value of e.m.f.
