clvi FACULTY OF SCIENCE of lbs foot run and CD one of w2 lbs foot run SheW how to determine the moment diagram and the reactions at Α and Shew also the points of inflection Electrical Engineering THIRD YEAK Give diagram of connections and show how you would test the accuracy of Quantity and an Energy Electric Supply Meter State the principles underlying the action of Hookham's Electric Supply Meter Would you employ "series" or "shunt" motor for the propulsion of Tramcar Give the reasons for your choice State the advantages to be gained by the series- parallel operation of Motors for Traction purposes State the advantages to be gained by the differential testing of dynamos and show how the test can be carried out in the case of direct currents when all the measurements are electrical Point out the characteristic differences between In- closed and Open Type Arc Lamps When working with alternate currents show why choking coil is used in series with the Arc Lamp In an alternate current Generator running on open circuit deduce from first principles the equation connecting the maximum Induction in the Armature the number of turns on the Armature the frequency and the reading on Voltmeter connected to the terminals of the machine What addition would you make to direct current Generator in order that it may be employed as phase Rotary Converter in the case of Rotary Converter transforming from alternate currents to direct currents how would you vary the relative excitations of the Converter and Generator in order to maintain maximum power factor for all loads the intermediate conductors being non-inductive
