when birds sit on transmission lines, the potential between
two legs of it, would be very low.Also, it body has its own
resistance to withstand minor current following from his
body thats why it doesn't get shock.

for examples it body offers resistance R= 1000 ohm (Approx.)
and potential difference between two legs V=1V (Approx.)

then current following from its body I=1/1000 = 0.001A
which doesn't harm its body.

The knee point of a current transformer is normally unique and known.So why in the nameplate of a CT they put the minimum value like this Vk> 400v.

A 230V dc shunt wound motor has an armature resistance of 0,15Ω.When operating on no load at 650 rev/min the armature current is 6A . The motor takes a full load current of 85A. Calculate the full load speed if the field flux is (i) maintained constant (ii)reduced by 0,03
