Q2\A/ A 8 pole de generator has 500 armature conductors and a useful flux of 0.05 wb. What will be the e.m.f. generated, if it is lap-connected and runs at 1,200 r.p.m.? What must be the which it is to be driven to produce the same e.m.f., if it is wave-wound?

A simple generator has a square armature 9.0 cm on a side. The armature has 80 turns of 0.59-mm-diameter copper wire and rotates in a 0.700-T magnetic field. The generator is used to power a lightbulb rated at 12.0 V and 25.0 W. Part A At what rate should the generator rotate to provide 12.0 V to the bulb? Consider the resistance of the wire on the armature. Express your answer to two significant figures and include the appropriate units. HA ? f = Value Units

A 4 pole generator with wave wound armature has 50 slots each having 26 conductors. The flux per pole is 0.01 Wb. (i) At what speed must the armature rotate to give an induced EMF of 230V is, (ii) What will be the voltage developed, if the winding is lap connected and the armature rotates at the same speed is,

A 6 pole wave wound d.c. shunt generator has 500 conductors. A generator delivers 50 kW of power at 250 voltage at full load. The resistance of the field circuit is 125 2. Actual brush shift is 10°. Then find the demagnetizing and cross magnetizing ampere turns per pole and how many additional turns must be wound on each pole to eliminate the demagnetizing effect.
