Chapter 11.3, Problem 16R

To determine

To Describe: The situation when a person is talking on a cell phone and he travels from one cell to another cell.

Explanation of Solution

Introduction:

The magnetic field that changes is generated by changing the electric field around a charge. Likewise, the electric field that changes is generated by changing the magnetic field around a charge. The electromagnetic waves are generated in an electric and magnetic field due to continuous charge.

In a cell phone, the sound wave is transmitted to and from a microwave tower using microwaves or radio waves. The towers are several kilometers apart and each covers an area called a cell.

If a person moves from one cell to another while he is talking on his mobile phone, then an automated control system transfer signal from one base station to another.

Conclusion:

Hence, an automated control system transfer signal from one base station to another.
