Question

An 1647 w toaster, a 1592 w electric frying pan, and a 81 w lamp are plugged into the same outlet in a 120-v circuit. (the three devices are in parallel when plugged into the same socket.). what current is drawn by the frying pan

Answer 1

Since all of the appliances ... and everything else in the house that's
plugged into a wall outlet ... are all in parallel, they don't have any
effect on each other.  They don't know about each other.  The
question asks about the frying pan, so the toaster and the lamp
have no effect  on the answer.

The frying pan has 120 V applied to it, and it produces 1592 watts
of heat.

Power = (voltage)·(current)

1592 watts = (120 v)·(current)

Divide each side by 120v:

Current = (1592 watts) / (120 volts)

Current = 13.27 Amperes
