Option 2 : Transistor
There are two kinds of voltage or current sources:
Independent Source: It is an active element that provides a specified voltage or current that is completely independent of other circuit variables.
The symbol for independent voltage and curent source:

Example: Alternator, DC generator, Battery
Dependent Source: It is an active element in which the source quantity is controlled by another voltage or current in the circuit.
The symbol for dependent voltage and current source:
