differance between current & voltage Source..??

OpenStudy (anonymous):

The difference is that a voltage source is one that tries to maintain the voltage across a load impedance constant for all values of load impedance.and a current source tries to supplies a constant current to a variable load impedance. If the internal resistance of a voltage source is very small then for all values of load impedance then almost constant voltage is obtained at load. And if the internal resistance of the voltage source is very high compared with the load impedance then it behaves as a current source with farely constant current flowing through load.
