What are the types of circuits?

An electrical circuit is the combination of different active and passive components such as resistors, capacitors, inductors, diodes, transistors etc. which form an electrical network. In a closed-loop circuit, the electric current flows from the source (such as battery) in the conducting material (e.g. wires and cables) to the load (i.e. light bulb) and hence returns back to the source.

What is Electronic Circuits?

Electronic Circuit is a type of electric circuit consisting of many electronic components such as diodes, transistors, resistors, capacitors etc. where at least one of active components must be presented in the circuit which further differentiates it from the electrical circuit. This way, it is known as an electronic circuit instead of an electrical circuit.

What is an Electrical Network?

A combination of different electric elements and components which are connected in any way (simple or complex configuration) is called an electric network. It is the same term used for an electric circuit but most commonly associated with the complex networks which are solved by network theorems.

Complex Networks

A circuit which contains many electrical elements such as resistors, capacitors, inductors, current and voltage sources (both AC and DC) where all the circuit components and elements are complexly configured is called a complex network. These kinds of networks can’t be solved easily by simple Ohm’s Law or Kirchhoff’s laws. If so, the number of equations will be more noticeable.

The easiest way to solve and analyze a complex network is using specific techniques such as network theorems i.e. Norton’s theorem, Thevenin’s theorem, Superposition theorem, star – delta transformation, Supernode and supermesh circuit analysis etc.

Open Circuit

A circuit which has no return path for current to flow in it (i.e. which is not completed) is known as an open circuit. In other words, a circuit where voltage tends to the EMF (of generating source) and no current is flowing at all is called an open circuit.

Example of an open circuit: A circuit with an open switch or blown fuse where the light bulb connected to the battery. So the bulb won’t glow as the circuit is not completed i.e. it is an open circuit and there is no flowing current in it.

Closed Circuit

A circuit which has a return path for current to flow in it (i.e. completed circuit) is known as closed circuit.

Example of a short circuit: A circuit with a close switch where the light bulb is connected to the battery. So the bulb glows as current is flowing in the filament of the bulb due to the completed circuit.

Short Circuit

A circuit which has a return path for current to flow in it where the value of resistance = zero. (i.e. completed or closed circuit without connected load) is known as short circuit. In other words, A circuit where voltage tends to zero and current tends to infinity is called a short circuit.

Example of a short circuit: A circuit with a close switch without load connected to the supply voltage. In other words, when a Phase or Line wire touches the Neutral wire without a load between them. In that case, the fuse will blow or the circuit breaker will trip. In the absence of proper protection, the short circuit may damage the appliance or cause a very serious injury.

Series Circuit

In this circuits, all the electrical elements (Voltage or current sources, inductors, capacitors, resistors etc) are connected in series i.e. There is only one path for traveling electricity e.g. These are single branch circuits.

Parallel Circuit

In this circuits, all the electrical elements (Voltage and Current sources, inductors, capacitors, resistors etc) are connected in parallel i.e. There are many paths for traveling electricity and the minimum branches in this circuit are two.
