Chapter 37: excercise 8 (page 1081)

The current in a Crookes tube is10nA. How many electrons strike the face of the glass tube each second?

Short Answer

Expert verified

Number of electrons=625脳108

Step by step solution

01

Given information:

We have given that

Current (I)=10nA

Time (T)=1s

Here we need to calculate the number of electrons striking the face of glass tube each second through the formulaI=QTwhere I is the current and Q is the total charge of all electrons flowing in the tube in the given time T.

02

Explanation:

Charge on electron (e)=1.6脳10-19C

Now, let the number of electrons be=N

According to the formula: I=QT

I=NeT Q=Ne

10nA=N1.6脳10-19C1s

N=625脳108
