Aresistor (resistance = r) is connected first in parallel and then in series with a 2.84- resistor. a battery delivers 8 times as much current to the parallel combination than it does to the series combination. determine the two possible values for r, the greater value being the answer to part (a).

the answer you are looking for is d. there are no holes for blood to enter or leave the system. your welcome

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.
