1011303TWO PORTS
Two Ports. A common use of electric circuits is to connect a source of electric energy or information to a load, often in such a way as to modify the signal in a prescribed way. In its basic form, such a circuit has one pair of input terminals and one pair of output terminals. Each of the four wires will have a current flow in or out of the circuit. Between any pair of terminals there will be a voltage. If the structure of the circuit is such that the current flow into one terminal is equal to the current flow out of a second terminal, then that terminal pair is called a port. The circuit of
