Question

When a hair dryer is plugged into a 220 V outlet,a current of 1.75 A flows into it.What is the power rating of the hair dryer?​

Answer 1

hope this helps u

$\huge{\mathcal{\pink{A}\green{N}\red{S}\blue{W} {E}\green{R}}}$

potential difference = 220V

current = 1.75A

$power=potential difference*current$

$\red{\boxed{p\:=\:v\:*i}}$

power = 220*1.75

           = 385W

$\boxed{\red{power\:=\:385\:watts\:is\:the\:answer}}$
