Question 1125841
The maximum value of I will be {{{ highlight( 40  )}}}amperes.   You can see this by noting that sin(X) always outputs a number in the range  [-1, 1].<br>

The time for one period is that value of t which gives {{{ 110(pi) t = 2pi }}} (angles are in radians).
  Solving this for t:  {{{ highlight(t = 2/110 )}}}sec   (about 0.0182 sec or 18.2ms)
