Which component of the microscope is found directly under the stage, and contains two sets of lenses that collect and concentrate light as it passes upward from the light source into the lens systems

CONDENSER

Explanation:

CONDENSER is the component of the microscope that is found directly under the stage, and contains two sets of lenses that collect and concentrate light as it passes upward from the light source into the lens systems. The condenser increases the resolution of light.

A microscope is an instrument that is used in laboratory to examine objects that can't be viewed with the naked eye. This is possible with as it is designed with lenses that aids in magnification of the objects.

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.
