open circuits and closed 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..

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 switch are connected together to form electrical h..

Ampere's law is a useful relation that is analogous to Gauss's law. Ampere's law is a relationship between the tangential component of magnetic field at points on a closed curve and the net current through the area bounded by the curv..

Ampere's law is a useful relation that is analogous to Gauss's law. Ampere's law is a relationship between the tangential component of magnetic field at points on a closed curve and the net current through the area bounded by the curve. Ampere's law is formulated in terms of the line in..

Arithmetic Circuits - 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 gates. Repeated addition gives multiplication. Rep..

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 a separate battery is required..
