Figure 3: A current amplifier (gray box) driven by a Norton source (i S, R S) and with a resistor load R L. Current divider in blue box at input (R S, R in) reduces the current gain, as does the current divider in green box at the output (R out,R L) The gain of an amplifier generally depends on its source and load terminations.
A dual of a relationship is formed by interchanging voltage and current in an expression. The dual expression thus produced is of the same form, and the reason that the dual is always a valid statement can be traced to the duality of electricity and magnetism. Here is a partial list of electrical dualities: voltage – current
Since the ladder is a series circuit, the current is the same throughout, and is given by the total voltage divided by the total series resistance (V/R eq). The voltage drop across any one resistor is I×R n , where I is the current calculated above, and R n is the resistance of the resistor in question.
Voltage divider or potential divider is used for circuits of that purpose. L-section is a common name for the topology in filter design. A network with three branches has four possible topologies. Figure 1.4. Series and parallel topologies with three branches
If a current I from a separate source is flowing through the ground conductor, the resistance R of the conductor will create a voltage drop along the cable ground of IR, so the destination end of the ground conductor will be at a different potential than the source end = Since the differential amplifier has high impedance, little current flows ...

The equations and their solutions are applicable from 0 Hz (i.e. direct current) to frequencies at which the transmission line structure can support higher order non-TEM modes. [2]: 282–286 The equations can be expressed in both the time domain and the frequency domain. In the time domain the independent variables are distance and time.
Power divider in microstrip technology. In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports.
