Directions : In the following questions, A statement of Assertion (A)...

The metallic body of the electrical appliance is connected to the 3rd pin which is an earth pin. By any chance if the metallic body gets connected to the LIVE line, current flows to earth through this pin without giving any shock to the user. Hence the assertion is true. Electric bulb does not have any metallic enclosure and hence there is no requirement of an earth pin. So, the reason is also true and properly explains the assertion.

Directions : In the following questions, A statement of Assertion (A)...

Assertion (A): Electric appliance with metal body has three electrical connections. But an electrical bulb has two electrical connections.
Reason (R): Three pin connection reduces chances of electrical shocks.

The correct answer is option 'A' - Both A and R are true and R is the correct explanation of A.

Explanation:
Electric appliances with metal bodies, such as refrigerators, washing machines, air conditioners, etc., have three electrical connections. This is because these appliances require an additional connection called the earth connection or ground connection.

1. Earth Connection: The earth connection is provided to prevent electrical shocks. It is a safety measure that helps in redirecting the electric current to the ground in case of any electrical faults or leaks. The earth connection is connected to the metal body of the appliance, and in case of any leakage current, it ensures that the current flows into the ground instead of passing through a person who may come in contact with the metal body.

On the other hand, an electrical bulb does not have a metal body and does not require an earth connection. It only has two electrical connections - one for the supply of electric current and the other for the return path of the current.

2. Two Pin Connection: A normal electrical bulb has a two-pin connection - one pin is connected to the live wire (supply wire) and the other pin is connected to the neutral wire. The live wire carries the electric current from the power source to the bulb, and the neutral wire provides the return path for the current back to the source.

3. Three Pin Connection: Electric appliances with metal bodies, as mentioned earlier, have an additional connection called the earth connection. These appliances have a three-pin plug, where one pin is connected to the live wire, one pin is connected to the neutral wire, and the third pin is connected to the earth wire. This third pin is longer and thicker than the other two pins and is designed to make the earth connection. It ensures that any leakage current is immediately redirected to the ground, reducing the chances of electrical shocks.

Therefore, the statement of Assertion is true, and the Reason provided is the correct explanation for it. The presence of a third pin in the three-pin connection of electric appliances with metal bodies reduces the chances of electrical shocks by providing an earth connection.

Read the following text and answer the following questions on the basis of the same:At power plant, a transformer increases the voltage of generated power by thousands of volts so that it can be sent of long distances through high-voltage transmission power lines. Transmission lines are bundles of wires that carry electric power from power plants to distant substations. At substations, transformers lower the voltage of incoming power to make it acceptable for high volume delivery to nearby end-users. Electricity is sent at extremely high voltage because it limits so-called line losses. Very good conductors of electricity also offer some resistance and this resistance becomes considerable over long distances causing considerable loss.At generating station, normally voltage is stepped up to around thousands of volts. Power losses increase with the square of current. Therefore, keeping voltage high current becomes low and the loss is minimized. Another option of minimizing loss is the use of wires of superconducting material. Super-conducting materials are capable of conducting without resistance, they must be kept extremely cold, nearly absolute zero, and this requirement makes standard superconducting materials impractical to use. However, recent advances in superconducting materials have decreased cooling requirements. In Germany recently 1 km of superconducting cable have been installed connecting the generating station and the destination. It has eliminated the line loss and the cable is capable of sending five times more electricity than conventional cable. Using superconducting cables Germany has also get rid of the need of costly transformers. Transformers generate waste heat when they are in operation and oil is the coolant of choice. It transfers the heat through convection to the transformer housing, which has cooling fins or radiators similar to heat exchangers on the outside. Flush point is a very important parameter of transformer oil. Flashpoint of an oil is the temperature at which the oil ignites spontaneously. This must be as high as possible (not less than 160° C from the point of safety). Fire point is the temperature at which the oil flashes and continuously burns. This must be very high for the chosen oil (not less than 200° C).Oil transfers heat from transformer winding by the process of
