Chapter 22: Q. 39 (page 625)

A smart phone charger delivers charge to the phone, in the form of electrons, at a rate of-0.75C/s . How many electrons are delivered to the phone during 30min of charging?

Short Answer

Expert verified

Delivered electrons are8.4脳1021electrons.

Step by step solution

01

Calculation for charge

Charge is,

Q=Ne

Where e=-1.6脳10-19C.

So,

N=Qe

The rate of accumulation of the electrons is ,

Qt

=-0.75C/s

For time t=30min,

Where,

t=30min=30(60s)

=1800s

So,

Q=(-0.75C/s)t

=(-0.75C/s)(1800s)

=-1350C

02

Calculation of electrons

Electron is,

N=Qe

=-1350C-1.6脳10-19C

=8.4脳1021electrons
