5.1 Linearization around operating pointĪn active network is a network that consists of at least one active source like a voltage source or current sourceĪ passive network is a network which does not contain any active device. Such networks are generally nonlinear and require more complex design and analysis tools. If the sources are constant (DC) sources, the result is a DC circuit.Ī network that contains active electronic components is known as an electronic circuit. Analysis of resistive circuits is less complicated than analysis of circuits containing capacitors and inductors. They are thus more easily analyzed, using powerful frequency domain methods such as Laplace transforms, to determine DC response, AC response, and transient response.Ī resistive circuit is a circuit containing only resistors and ideal current and voltage sources. Linear electrical networks, a special type consisting only of sources (voltage or current), linear lumped elements (resistors, capacitors, inductors), and linear distributed elements (transmission lines), have the property that signals are linearly superimposable. 
An electrical circuit is a network consisting of a closed loop, giving a return path for the current. Here,, according to Ohm's Law.Īn electrical network is an interconnection of electrical elements such as resistors, inductors, capacitors, voltage sources, current sources and switches. A simple electric circuit made up of a voltage source and a resistor.
