To find the effective current delivered by the generator, we need to understand that the effective current in an AC circuit is known as the root mean square (RMS) current. However, given the nature of the question and that it is missing specific information about the type of current (AC or DC), I will assume it is an AC generator.
For an AC generator, the effective or RMS value of the current (I_rms) is related to the maximum or peak current (I_max) by the following relationship:
\[ I_{rms} = \frac{I_{max}}{\sqrt{2}} \]
Given that the maximum current (I_max) is 0.17 A, we calculate:
\[ I_{rms} = \frac{0.17 , \text{A}}{\sqrt{2}} \approx \frac{0.17 , \text{A}}{1.414} \approx 0.12 , \text{A} \]
So the effective current delivered by the generator is approximately 0.12 A.
Thus, the correct choice from the options provided is:
0.12 A
