# Circuit analysis

The video course introduces the analysis and design of linear circuits. The course covers the relationship of voltage, current, resistance and power such as Ohm's Laws. Circuit A current from one terminal of a generatorthrough load component s and back into the other terminal. A circuit is, in this sense, a one-port network and is a trivial case to analyse. If there is any connection to any other circuits then a non-trivial network has been formed and at least two ports must exist.

Often, "circuit" and "network" are used interchangeably, but many analysts reserve "network" to mean an idealised model consisting of ideal components. Most often, an input port and an output port are discussed and the transfer function is described as gain or attenuation.

Component transfer function For a two-terminal component i. A three or more terminal component effectively has two or more ports and the transfer function cannot be expressed as a single impedance. The usual approach is to express the transfer function as a matrix of parameters.

These parameters can be impedances, but there is a large number of other approaches see two-port network. Equivalent impedance transforms A useful procedure in network analysis is to simplify the network by reducing the number of components. This can be done by replacing the actual components with other notional components that have the same effect.

A particular technique might directly reduce the number of components, for instance by combining impedances in series. On the other hand, it might merely change the form into one in which the components can be reduced in a later operation.

For instance, one might transform a voltage generator into a current generator using Norton's theorem in order to be able to later combine the internal resistance of the generator with a parallel impedance load. A resistive circuit is a circuit containing only resistorsideal current sourcesand ideal voltage sources. If the sources are constant DC sources, the result is a DC circuit. Analysis of a circuit consists of solving for the voltages and currents present in the circuit. The solution principles outlined here also apply to phasor analysis of AC circuits. Two circuits are said to be equivalent with respect to a pair of terminals if the voltage across the terminals and current through the terminals for one network have the same relationship as the voltage and current at the terminals of the other network.An electrical network is an interconnection of electrical components (e.g.

batteries, resistors, inductors, capacitors, switches) or a model of such an interconnection, consisting of electrical elements (e.g. voltage sources, current sources, resistances, inductances, capacitances).An electrical circuit is a network consisting of a closed loop, giving a return path for the current.

Instead of analysing each passive element separately, we can combine all three together into a series RLC circuit. The analysis of a series RLC circuit is the same as that for the dual series R L and R C circuits we looked at previously, except this time we need to take into account the magnitudes of both X L and X C to find the overall circuit reactance.. Series RLC circuits are classed as. Circuit analysis is a very intense, math-oriented field. The objective is to be able to predict a voltage or current at ANY spot in a circuit, and be sure the circuit is .

Circuit Analysis Developing an understanding of circuits is the first step in learning about the modern-day electronic devices that dominate what is becoming known as the "Information Age." A basic circuit type, the series circuit, is a circuit in which there is only a single current path.
