From the fundamental quantity M, L and T derived dimensions of (1) Work
(2) Momentum
(3) Energy
(4) Density
(5) Pressure gradient​

measure their densities same density, same sub

because if the tool that you are using is not balanced it there would be false mass.

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.
