Dependent Voltage (Current) Sources

Dependent Voltage Sources :
Some voltage (current) sources have their voltage (current) values proportional to some other voltage or current in the circuit. They are called dependent voltage (current) sources or controlled voltage (current) sources.Thus there are 4 types of dependent sources.

1. Voltage dependent voltage source

2. Current dependent voltage source

3. Voltage dependent current source

4. Current dependent current source.
Variables in brackets are the controlling variables whose values affect the value of the source.
