IN WHICH MODE THE TRANSFORMER WILL GET A MAXIMUM OUT PUT VOLTAGE. ASKED FOR POWER GRID EXAMINATION STAT-STAR,STAR-DELTA,DELTA-STAR,DELTA-DELTA
why ahould you show client/engineer activities clearly on the project plan
how will reduce the voltage. if 12volt/250ma transformer toreduce 6 volt
why the earth is taken minimum in supplying? wather it the proportional factor to getting work any equipment or a power plant?
What Is HO factor in power selection
In ups static switch if i gives the supply at output end it will open the circuit in stactic switch or not if it will open then how it operates.
resitance in ac=1.6*resistance in dc
what is back emf?
what is feed back and what are feed back amplifiers?
What is the drawback of static coefficients?
