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..

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, Gustav Robert Kirchhoff developed two laws..

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 ..

The devices which deliver electricity are called the 'sources'. 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 loads, and the switches are conne..

>The earth wire is much thicker in size and is made of copper. One end of it is connected to a copper plate buried deep under the earth. The earth connection is made to the electric meter and then to the main switch. In our homes, we receive supply of electric power through a ma..

Domestic Electric Circuit - Electric power is usually generated at places which are far from the places where it is consumed. Distribution of Electricity from Grid The power is transmitted over long distances at high voltage to minimize the loss of energy dur..

Electric power is usually generated at places which are far away from the places where it is consumed. At the generating station, the electric power is generated at 11,000 volts. This voltage alternates at a frequency of 50 H..
