1) A 4 pole DC Shunt generator runs at 750rpm and generates has a useful flux per pole of 0.07Wb. Generator is a wave-wound and has 792 conductors and the total resistance of the armature winding is 0.08 Ohm. Calculate the terminal voltage if the armature current is 50A
2) In a 120V compound generator, the resistances of the armature shunt and series windings are 0.06 ohm, 25 Ohm, and 0.04 Ohm respectively. The load current is 100A at 120V, find the induced EMF and the armature current of the generator.
Analysing spectrum anlyser output, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates the follow..
