O 1 (glass) & 2 (wood)
O 1 (graphite ) & 2 (wood)
O 1 (wood) & 2 (graphite)

an energy transformation flow diagram is shown

where is it ?

it's a b and

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.
