Answer:

The maximum current is 40 Amperes

Step-by-step explanation:

The function describes alternating current following a cos function with amplitude of 40A. The cosine will attain its maximum when its argument reaches 0 and every 2pi period. The maximum value of the cos() function is 1. Therefore the maximum of the function describing the current will be 40*1=40 Amperes.
