Question 67246: The current I that flows through an electrical appliance is determined by
I = square root of (P/R),
where P is the power required and R is the resistance of the appliance. To use this formula express the current in amperes (A), the power in watts (W), and the resistance in ohms (o). If an electric hair dryer has a resistance of 60o and draws 4.5 A of current, how much power does it use? Answer by Nate(3500) (Show Source):
