Electric circuits

An electric circuit is defined as a closed-loop network of interconnected components, such as a power source, wires, and a load, which allows electric current to flow continuously from the source to the load and then return to the source. The electric circuits consist of conducting wires, which have a very low resistance, allowing the electric current to flow through them freely.

What are the main components of an electric circuit?

The main components of an electric circuit are

Power source: A power source provides the voltage (or potential difference) for allowing the current to flow through the circuit.

Wires: The wires allow the continuous flow of current in the electric circuit.

Load: A load provides the output electric energy.

Control: For controlling the current flow in the circuit, a switch is used to open or close the circuit.

Types of electric circuits

Electric circuits

The types of electric circuits are

 Closed circuit: A closed circuit is a continuous electric circuit where an electric current flows from a power source to a load uninterruptedly.

Open circuit: An open circuit is an electric circuit where the flow of electric current is interrupted. If the circuit is not closed, or if the switch is in the off position, it is considered an open circuit.

Features of an open circuit

No current flow: When there is no current flow in a circuit, then it is considered an open circuit.

Infinite resistance: When the current is zero, the resistance in the circuit is considered to be infinite.

Presence of voltage: When voltage is present in an electric circuit, but in the absence of a closed path, the current can't flow.

Series circuit: A series circuit is a circuit in which all elements of the circuit are arranged in a single conducting line. The current through all the elements is the same, but the voltage is different across the elements in the circuit.

The equivalent resistance in a series circuit is the total of all the resistances connected in series in the circuit.

Req=R1+R2

Electric circuits

Parallel circuit: A parallel circuit is a circuit in which the elements of the circuit are arranged in multiple conducting lines. The current through the elements of a parallel circuit is different, but the voltage is the same across the elements of the circuit. 

The equivalent resistance in a parallel circuit is the total of the reciprocals of all the resistances connected in parallel with the circuit.

1/Req= 1/R1 + 1/R2

Req=R1R2/R1+R2
