When operated on a household 110.0-V line, typical hair dryers draw about 1650 W of power. We can model the current as a long straight wire in the handle. During use, the current is about 2.25 cm from the user\’s hand. What is the current in the dryer
Question
Answer:
Current in the hair dryer will be equal to 15 A
Explanation:
We have given that household is operated at 110 volt
So potential difference V =110 volt
Power drawn by hairdryer is P = 1650 watt
We have to find the current in the hair dryer
We know that power is given as P = VI, here V is potential difference and I is current
So [tex]1650=110\times I[/tex]
I = 15 A
So current in the hair dryer will be equal to 15 A
