To determine the effective current gain of the amplifier with negative feedback, we need to use the formula for the gain with feedback. This formula is:

Af = A / (1 + A*β)

Where:
Af is the gain with feedback,
A is the gain without feedback, and
β is the feedback factor.

In this case, the gain without feedback (A) is 200 and the feedback factor (β) is 0.012 (current attenuation).

Substituting these values into the formula, we get:

Af = 200 / (1 + 200*0.012)

Now, calculate the value inside the parentheses:

1 + 200*0.012 = 1 + 2.4 = 3.4

Then, divide the gain without feedback by this value:

Af = 200 / 3.4 = 58.82 (approximately)

So, the effective current gain of the amplifier with negative feedback is approximately 58.82.
