Frequency

Explanation:

A period is the number of revolutions in a minute.

Also, frequency can be defined as number of oscillation per unit time.

Mathematically, frequency is given by the formula;

Thus, we can deduce that frequency of an oscillation is the inverse of the period (time) of oscillation.

Mathematically, period is expressed as;

This ultimately implies that, an object's period of oscillation can always be used to solve for frequency.

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.

it would stay the same
