Question

When operated on a household 110.0 V line, typical hair dryers draw about 1650 W of power. The current can be modeled as a long, straight wire in the handle. During use, the current is about 2.75 cm from the user's hand. What is the current in the hair dryer

Answer 1

Answer:

Explanation:

voltage, V = 110 V

Power, P = 1650 W

P = V x i

where i is the current in the hair dryer

1650 = 110 x i

i = 15 A

Thus, the current in the hair dryer is 15 A.
