WHAT IS THE SPECIFICATIONS CONSIDERED DURING DESIGN FOR THE OVER CURRENT RELAY?3 2772
why we use mostly 3-phase but not 4-phase and 5-phase what is the difference between them1 1766
Why underground cables are used to connect transformers?In addition how are they again connected to lines after step up or step down?1 2829
if the voltage across the lamp drops by 1%, the power drawn will be reduced by how many %?5 18724
is the power of a single phase induction motor(Fans) is constant under varying speeds?4 3113
Why current leads the voltage in case of capacitor load? Why voltage leads the current in case of inductive load? Why both are with in phase in case of restive load?
apti mainly on logical reasoning, verbal and non-verbal ability (70 percent) and remaining technical. I was in ee but technical had mech ques like on turbines and welding.
