Current Source

What is the difference between a current source and a voltage source?

A constant current source delivers a constant current irrespective of the load applied whereas a voltage source delivers a constant voltage irrespective of the load applied.

Is a current source active or passive element?

Since current source performs the task of delivering constant current, it is an active device in the circuit.

What is the reason for high resistance in current sources?

A current source has high impedance to ensure that even when external load is increased or decreased , it has negligible effect on resistance thereby ensuring a constant current generation.



Current Source

A current source is an integral part of electronic circuits which is used for supplying current in the circuit. In this article, we will discuss these current sources along with their types.
