A simple electric circuit made up of a voltage source and a resistor. Here,

An electrical network is an interconnection of
electrical components (e.g.
switches) or a model of such an interconnection, consisting of
electrical elements (e.g.
capacitances). An electrical circuit is a network consisting of a closed loop, giving a return path for the current.
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. They are thus more easily analyzed, using powerful
frequency domain methods such as
Laplace transforms, to determine
AC response, and
A resistive circuit is a circuit containing only resistors and ideal current and voltage sources.
Analysis of resistive circuits is less complicated than analysis of circuits containing capacitors and inductors. If the sources are constant (
DC) sources, the result is a
DC circuit. For a random resistor network, the effective resistance and current distribution properties of the network can also be modeled in terms of graph measures and geometrical properties of network.
A network that contains
electronic components is known as an
electronic circuit. Such networks are generally nonlinear and require more complex design and analysis tools.
