what is the difference of independent and dependent voltage source

Question

anonymous · Answer

an independent voltage source maintains a constant voltage across it's terminals no matter whatever current is drawn from it. theoretically speaking an ideal independent voltage source should be able to maintain a constant fixed voltage across it irrespective of whether the current flowing through it is 0 or +infinity or -infinity. but a practical independent voltage source due to the presence of internal resistance shows a change in the terminal voltage  with respect to change in current flowing across it.
   a dependent voltage source has it's terminal voltage as a function of current or voltage of another element. as the independent current or voltage variable associated with the dependent voltage source changes the voltage across it changes accordingly.
