.
𝑖 = 20 sin(100𝜋𝑡 + 0.4)
what is the time in milliseconds when the current first reaches its maximum value
~~~~~~~~~~~~~~~~~~~~~~

It will happen when the argument first time will reach the value of pi%2F2

   100*pi*t+0.4 = pi%2F2.


It gives

   t = %28pi%2F2+-+0.4%29%2F%28100%2Api%29 = %283.14159265358979%2F2-0.4%29%2F%28100%2A3.14159265358979%29 = 0.0037267605.


The dimension is the same as the dimension of "t" in the formula, which (dimension) is not given in the post.

Solved.
