What is the Difference between network and circuit?

Answer 1

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.An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit.

The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load". The load of an electrical circuit may be as simple as those that power electrical appliances like refrigerators, televisions, or lamps or more complicated, such as the load on the output of a hydroelectric power generating station.

Answer 2

An electrical network is an interconnection of electrical

elements such as resistors, inductors, capacitors,

transmission lines, voltage sources, current sources, and

switches.

An electrical circuit is a network that has a closed loop,

giving a return path for the current. A network is a

connection of two or more components, and may not

necessarily be a circuit.

Answer 3

A gate is a specific instantiation of a circuit that is intended to perform some boolean logic function.

There are many other specific instantiations of a circuit that perform other functions unrelated to boolean logic (e.g. amplifier, oscillator, modulator, demodulator, mixer, converter, circulator, gyrator, tank, rectifier, voltage doubler, voltage trippler, voltage regulator, current regulator, power inverter, low pass filter, high pass filter, band pass filter, band reject filter, automatic gain control, automatic frequency control, phase locked loop, impedance matcher, clipper, limiter, operational amplifier, integrator, differentiator, multiplier, summation, logarithm, antilogarithm, voltage comparator, delay, debouncer, register, latch, multiplexer, demultiplexer, encoder, decoder, digital comparator, line driver, line receiver).

A gate is one type of circuit, there are literally billions of different types of circuits
