Q. Consider themagnetic circuit of Figure. Let the cross-sectional area AC of the core, be
16 cm2 , the average length of the magnetic path in the core lC be 40 cm, the number of turns N of the excitation coil be 100 turns, and the relative permeability µr of the core be 50,000.
For a magnetic flux density of 1.5 T in the core, determine:
(a) The flux φ
(b) Total flux linkage λ(= Nφ).
(c) The current required through the coil.
Two projects using the principle of functional independence, increases system accuracy?
Q. Counter-controlled analog to digital converter? Figure shows the block diagram of a counter-controlledA/Dconverter. Resetting the binary counter to zero produces D/A output
a single phase is supplied with sinusoid voltage v(t)=200cos(377t).the resulting instantaneous power is p(t)=800+1000cos(754t-36.7). find
Q. emf produced by windings? The time variation of emf for a single conductor corresponds to the spatial variation of air-gap flux density. By suitable winding design, the harm
