Answer:
Option B
Step-by-step explanation:
Note that the current generated by an AC generator is an alternating current.
An alternating current is one which continually changes its polarity. That is, it oscillates and changes its magnitude and direction
Based on the points stated above, we can describe the current generated by an AC generator as a current that oscillates direction and magnitude between 0 and maximum.
This means that an alternating current does not only change its direction, it changes its magnitude too.
