tell me some type of questions throught which i can prepare for exam and do my best
Why in medium voltage system(3.3kv to 33kv, neutral is earthed with either resistance, reactance or neutral grounding resistance?
what is thermal setting and magnetical setting?
how to read AWG n how to convert AWG reading into mm?
a 100mva,400/200v transformer has leakage impdce of 10% draws a steady state line currentof---------------
Why does the power consumed is always constant even if a fan speed is altered?
Why 60Hz frequency is used in America what are all the benifits?
v=r*i this means when voltage increases current also increases at constant resistance.... p=v*i this means when voltage increases current decreases to maintain the power constant which one is true...
why dc is not given to transformer
What is the GNA & MNA in armature reaction of Dc Generator
