Energy Conversion Devices Question Paper
Can you please provide the previous year question for Energy Conversion Devices? Hello dude as you want the previous year question for Energy Conversion Devices so here I am providing you BPUT Previous Year Question of Energy Conversion Devices (ECD), please have a look…. 1.Show that the energy stored in a magnetic field is equal to the area between the ψ-i curve for the system and the flux linkage (ψ) axis. 2.Show that the field energy in a linear magnetic system is given by:- Wf = ½ Li2 = ½ ψi = ½L ψ² 3.Distinguish between singly excited and doubly excited systems. 4.For a singly linear magnetic system, derive an expression for the electromagnetic torque. 5.Define field energy and coenergy. 6.Why most practical energy conversion devices use magnetic field as the coupling medium between electrical and mechanical system?
