You should have put more effort in to your assignment.

This is NOT a homework cheat site.

Truck question.

In REALITY, the starting current peak will be the same or even worse. Only the duration changes.

Use a tong meter to measure your starting current of your star delta starter. If you not able to catch the tong meter deflection speed then hook it up with a recorder and record it.
