Hello everyone,
I'm getting WA verdict but can't find the bug. Please help me to find the bug.
Got AC.

Use search by problem number (537) and check your program for input in that threads.

U=120V and I=5.36A. What is the reason for calculating p? I cant understand ?
There was a p who has P=560W Which was destroyed by U=291.89V.
No chance if P=111.11W and I=3.004A.
