What is Earth wire?

Read the given passage and answer the following questions: The home electrical connection consists of 'live','neutral' and 'earth wires. The 'live' and the 'neutral' wires have potential difference of 220 v. The earth ire is connected to ground. Due to a fault in the equipment or if the plastic coating on the 'live ' and the neutral wires gives away the two wires come in contact with each other and a large current flows through it producing heat . If any inflammable material (such as wood , cloth , plastic etc). exists around that place it can catch fire. Therefore a fuse wire is used as a precautionary measures. Write the function of a fuse?

Complete the paragraph Select the appropriate options and complete the following paragraph. (neutral, earth, live, series, _ potential difference, parallel, 220 V, 110 V) There are three types of wires used for domestic connections. The wire which is red or brown in colour through which current enters is called as______ wire. The wire which is blue or black in colour through which current retums is called as_______ wire. The wire which is yellow or green in colour and used for safety purposes is called as________ wire. Various domestic appliances are connected in________ combination so that_______ across every appliance remains the same. In India, the voltage difference between the live and neutral wires is about _______.

Answer the following questions : In a domestic electric supply in India, what is the potential difference between the live wire and the neutaral wire?

Two uniform wires of a the same material are vibrating under the same tension. If the first overtone of the first wire is equal to the second overtone of the second wire and radius of the first wire is twice the radius of the second wire, then the ratio of the lengths of the first wire to second wire is

A composite wire is prepared by joining a tungsten wire and steel wire Both the wires are of the same length and same area of cross section. If this composite wire is suspended to a rigid support and a force is applied to its free end, it gets extended by 3.25 mm. Calculate the increase in length of tungsten wire and steel wire separately.

Give scientific reasons. Fuse wire is made from the material with low melting point.
