Chapter 27: Q. 12 (page 762)

The current in an electric hair dryer is 10.0A. How many electrons flow through the hair dryer in 5.0min?

Short Answer

Expert verified

The number of electrons flows through the hairdryer in5.0minis1.875脳1022.

Step by step solution

01

Given Information

Current=10.0A

Time=5.0min

02

Explanation

The number of charges is connected to the total charge,

Q=Ne鈬�N=Qe

By the definition of intensity, express the charge passed at a given time as a function of the intensity as

I:=Qt鈬�Q=It

In combining, we have

N=Ite

Substitute the values,

role="math" N=10A脳5s脳60s1.6脳10-19C

role="math" localid="1648897689414" =1.875路1022

03

Final Answer

Hence, the number of electrons flows through the hairdryer in5minis1.875路1022.
