Understanding of independent and dependent sources

-
  In an electrical circuit, a source is a device that provides electrical energy to the circuit. Sources can be classified as either independent or dependent. An independent source is a source that can produce an electric potential (voltage) or an electric current without being influenced by the circuit. Examples of independent sources include batteries, generators, and power supplies. A dependent source is a source that produces an electric potential or an electric current based on the voltage or current in the circuit. Examples of dependent sources include transistors and thermocouples. The behavior of a circuit with an independent source is determined by the characteristics of the source and the resistive elements in the circuit. The circuit will operate the same way regardless of the current or voltage in the circuit. The behavior of a circuit with a dependent source is more complex, as the source produces a current or voltage that is dependent on the current or voltage in
