Circuits are pathways or networks that allow the flow of electrical current between different components or elements. Circuits are fundamental to the functioning of electronic devices and systems This article talks about what are circuits, types of circuits, series circuits, parallel circuits, and various other types of circuit along with it’s properties. Table of Content What are Circuits?Circuits or Electrical Circuits are defined as a closed loop through which electricity can flow. These closed loops, or paths, are formed by a network of electrical components. Circuits are closed paths that have the same starting and ending points. The paths of the circuits are constructed with the help of electrical wires. The circuit contains electrical components like bulb, battery, electric wire, switch, etc. The point from which electrons start flowing is termed the source, while the point where electrons leave the circuit is termed the return. Types of CircuitsDepending on the types of connection and power source used, circuits can be classified into various types. Based on the connection there are primarily two types of circuits:
Series CircuitsSeries Circuits are defined as a type of circuits in which the electrical components or resources are arranged one after other. This type of connection is also termed as an end-to-end connection or cascade connection. In the series circuit there is only one path of the flow of current. In this circuits, the amount of current that flows the all the components is same.
Properties of Series circuit
Example: If 2 resistors of 3 ohm and 4 ohm are connected in series. What is the resistance of the circuit? Solution:
Parallel CircuitsParallel circuits are defined as a type of circuit in which various electrical components or resources are connected across one another in parallel. This circuit contains two or more paths for the flow of electric current. In this circuit the amount of voltage across each resource or components is constant or same. The amount of electric current through each component is variable.
Properties of Parallel Circuits
Example: If 2 resistors of 3ohm and 4ohm are connected in parallel. What is the resistance of the circuit? Solution:
Difference between of Series and Parallel CircuitsThe difference between series and parallel circuit is tabulated below:
Some Other CircuitsApart from the above there are other circuits as well. These other types of circuits are mentioned below:
Let’s discuss these circuits one by one. AC CircuitsAC circuits are defined as a type of circuit in which electricity flow and it’s magnitude changes from zero to its maximum value. Simply we can say, AC circuit uses alternating current power source. In AC circuits, the direction of flow of current changes alternatively. The voltage level in a AC circuit will vary in sinusoidal form. To perform long-distance power transmission we prefer the use of AC circuit. In AC circuit, there is a higher risk of electric shock. AC voltage: V = V0sinωt AC current: I = I0sinωt
DC CircuitsDC circuits are defined as a type of circuit in which the current flow only in a single direction. It is generally used in solar cells, batteries, electronic devices, etc. To perform simple applications, we mostly prefer DC circuits. The voltage level in a DC circuit is constant. To perform short-distance power transmission we prefer the use of AC circuit. In DC circuit, there is a low risk of electric shock.
Open CircuitsOpen circuit is defined as an electric circuit in which there is no flow of electric current through the circuit. In an open circuit, the terminals are not connected with each other. This type of circuit generally consists of path which are incomplete. It is generally used to represent the off state of the circuit. Example of open circuits include socket, flashlight etc.
Closed CircuitsClosed circuit is defined as an electric circuit in which there is flow of electric current through the circuit. In a closed circuit, the terminals are connected with each other. In a closed circuit, the path is complete. It is generally used to represent the on state of the circuit.
Series-Parallel CircuitSeries-Parallel Circuit are circuits in which there is use of both series and parallel type of circuits. This circuit includes the features of both the circuit and improves its efficiency.
Linear CircuitLinear circuit is an electric circuit in which the present elements or characteristics, their values does not change. It remains constant and does not get affected by any change in voltage or current flowing in the circuit.
Non-linear CircuitNon Linear circuit is an electric circuit in which the present elements or characteristics, their values does change. The properties or characteristics values are variable and does get affected by any change in voltage or current flowing in the circuit.
Unilateral CircuitsUnilateral circuit is defined as a circuit in the properties or characteristics of the circuit changes when either the current direction or voltage direction changes. This type of circuit allows the flow of current only in one direction. Example: Diode Rectifier
Bi-lateral CircuitsBi-lateral circuit is defined as a circuit in the properties or characteristics of the circuit does not change when either the current direction or voltage direction changes. This type of circuit allows the flow of current in two direction without any change in the behaviour of circuit.
Star Delta CircuitA star-delta circuit is also known as a star-delta starter. It is circuit present in the speed control system of three-phase induction motors. This technique involves connecting the motor windings in a star (Y) configuration during starting and then switching to a delta (Δ) configuration once the motor reaches a certain speed
Parts of CircuitA circuit consists of following parts:
Uses of CircuitsThe different applications of circuits are tabulated below:
ConclusionElectrical Circuits are important concept in electrical field. This article discusses that circuit are a closed loop through which electric current flows. There are two types of circuits that is series and parallel circuits. Series circuit involve connection in which all the electrical components are arranged in a single path. While in parallel circuit, there are two or more paths for the flow of current. We have also learnt various other types of circuits in this article.
