Answer Posted / bharani

When you isolate yourself from the ground by standing on an
insulator and touch a live wire, depending on the
resistivity of the inulator, a small current may flow
through your body to the ground and if it is negligible, you
may not feel anything. but if you wet your body and carryout
the the same experiment, then you may be at risk of a shock
as yor body resistance would have come down drastically.All
said and done, the resistivity of the material chosen as
inulator is very important.

sir pls send the je exam - 2008 and other model question papers..

Why reactive power is needed in a power system? How is it being absorbed or delivered by alternators? For reactive power control we are changing excitation but reactive power absorbing or delivering related to stator. How these two are interlinked? i want a detailed explanation with necessary expressions and figures?
