(a) Source of electric current.
Answers
Answer:
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. A current source is the dual of a voltage source.
Answer:
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.
Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V
A current source is the dual of a voltage source. The term current sink is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source driving a resistive load. There are two types. An independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
