True or false
When a live wire and a neutral wire come in contact with each other,it may cause short circuit

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. What is short circuit?

Two similar thin equiconvex lenses, of focal length f each, are kept coaxially in contact with each other such that the focal length of the combination is F_1 . When the space between the two lenses is filled with glycerin (which has the same refractive index (mu = 1.5) as that of glass) then the equivalent focal length is f_2 . The ratio F_1 : F_2 will be:

True or false The production of heat in a wire when connected to electric circuit is called heating effect of an electric current.
