Textbook Question
Chapter 18, Problem 1P
Discuss, in your own words, the difference between a controlled and an independent source.
Expert Solution & Answer

To determine
The difference between an independent and a controlled source.
Explanation of Solution
Independent source:
- Sources whose magnitudes are not dependent on the network to which they are attached are called independent sources.
- Their characteristics remain the same always, even when they are completely isolated.
Controlled sources:
- They are also called the dependent sources.
- The magnitudes of these sources are dependent on some other current or voltage in the circuits.
- They are represented by a diamond sign.
