Ideal Sources

Q1: What is an ideal voltage source?
A1: An ideal voltage source is a two-terminal element that guarantees a fixed voltage across its terminals, regardless of the current through it.

Q2: What is an independent current source?
A2: An ideal current source is a two-terminal element that guarantees a fixed current through its terminals, regardless of the voltage across it.

Q3: What are independent sources?
A3: Independent sources are sources whose guranteed voltage/current does not depend on any parameter of the circuit.

Q4: What are dependent sources?
A4: Dependent sources are sources whose guranteed voltage/current depends on a separate circuit parameter. The four flavors are:
1. Voltage-Controlled Voltage Source (VCVS)
2. Current-Controlled Voltage Source (CCVS)
3. Voltage-Controlled Current Source (VCCS)
4. Current-Controlled Current Source (CCCS)
