Generally electrical appliances such as an electric bulb, geyser, heater, etc. are rated with power and voltage. If a bulb is rated 100W - 250V, it means that when a bulb is lit on a 250V supply, it consumes 100 W of electric power. ..

To avoid the risk of electric shocks, the metal of an electrical appliance is 'earthed'. Earthed means to connect the metal case of the appliance to the earth (at zero potential) by means of a metal wire (copper) called the earth wire. One end of the earth w..

Usually an electric appliance such as a heater, an iron, etc. are fitted with all the 3 wires namely live, neutral and earth. The earth wire is connected to the metallic body of the appliance. This is done to avoid accidental shock. Suppose due to some defect, th..

Introduction - Electricity is one of the most important sources of energy. Lights, fans, motors, radios and television are some common appliances which work on electricity..

>The fuse is always connected in the beginning of the circuit before any appliance is connected, so that the fuse may melt before the appliance is damaged. The fuse wire must be of a current rating less than the maximum current which a circuit or an appliance..

>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..

Summary - Electric potential is the condition that determines the flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit of positive charge from infinity to that point. Electrical potentia..

Introduction - Appliances used in our day to day life are based on the principles of electricity and magnetism. Electricity is one of the most important sources of energy. Lights, fans, motors, radios and television are some common appliances which work on ..
