Series Voltage Regulators
... voltage divider law that states that the voltage drop across any two series resistors is proportional to the Ohms ratio of the resistors. If one resistor is 10 times bigger than another it will have 10 times the voltage drop across it. This concept does not change if one of the “resistors” is a Zene ...

31.63. Model: The battery and the connecting wires are ideal
... The figure shows the two circuits formed from the circuit in Figure P31.63 when the switch is open and when the switch is closed. Solve: (a) Using the rules of series and parallel resistors, we have simplified the circuit in two steps as shown in figure (a). A battery with emf E = 24 V is connected ...

... An ideal voltage source is independent of the current through it. A (more) practical voltage source is modeled by an ideal voltage source in series with a resistor. This more closely approximates “real” voltage sources. Ideal -vs- Practical Current Source An ideal current source is independent of ...

... A second-order circuit is given in this problem. It has two resistors, one capacitor, and one inductor. Firstly, we want to determine the transfer function, which is the s domain ratio of the output voltage to the input voltage. Let’s convert the circuit into s domain. For a resistor, the impedance ...

... It has two pairs of terminals, so it that can be viewed as a two-port network. Firstly, let’s label the terminal characteristics of the two ports. We can see that there are four terminal variables. There are two equations to relate these variables together in terms of z parameters. Let’s take a look ...

Network analysis (electrical circuits)
A network, in the context of electronics, is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, every component in the network. There are many different techniques for calculating these values. However, for the most part, the applied technique assumes that the components of the network are all linear.The methods described in this article are only applicable to linear network analysis, except where explicitly stated.
