0.55x745.7j and a calculator

iron would move it is magnetic there is a mag field around the current in the wire

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
