all about circuits

An electric circuit is a compete or closed path through which the charge can flow. When the switch is open or the circuit is broken, it is called the open circuit. Electric current will not flow through the open circuit...

Your everyday experiences have familiarised you with many electric circuits. Let us take an example of an electric circuit with a battery (a source of electricity), toaster and a switc..

A circuit in which the output is uniquely defined for each combination of inputs x 1 , x 2 , x 3 is called a combinatorial circuit..

Telephone Circuits - Two-way operation is essential for satisfactory telephone service, and many of the problems of the industry arise from this fact. A simplified circuit for obtaining two-way operation is shown in the below figure. This is called a local-battery system because..

Arithmetic operations such as addition, subtraction and complex operations such as multiplication, division etc., are performed by using digital circuits called adders, which again consists of basic logical gate..

Two combinatorial circuits, each having inputs x 1 , x 2 , x 3 , x 4 ,x n and a single output are said to be equivalent if their input/output tables are identica..

AC Circuit Containing Resistance, Inductance and Capacitance Circuit (LCR in series) - When an AC source is connected in a circuit with a resistance and a reactance together, the current varies initially in a complex way. After sufficient time, a sinusoidally varying c..

An electric fuse is a device which is used to limit the current in an electric circuit. The use of a fuse is to safeguard the circuit and the appliances connected in the circuit from being damage..

Electric Circuits and their Components - The devices which deliver electricity are called the 'sources'and lamps, electric engines, etc. which consume electricity are called 'loads'. Switches are used to switch the loads on and off whenever necessary. Hence, the source, the load, and the ..

Electric Circuits and Kirchhoff's Rules - In many electrical circuits, Ohm's law cannot be applied. This happens when there is more than one source of emf in the circuit or when resistors are connected in a complicated manner. To solve such complex circuits, ..
