... If we set I2 at zero, we can find z11. [math equation] The voltage that crosses the first port is V1. Let’s look at the top node. We can label the current flow through the two resistors as I3 and I4. Based on the Kirchoff Current Law, we know that I1 should be equal to the sum of I3 and I4. [math eq ...

Current source
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. The term constant-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 resistor 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.
