    Make your point clear first, You're saying that There will be short circuit because insulation will melt and earth wire and live wire will interact to cause a fire. And then you mention that there will be alarge current to melt the insulation, where did that large current come from?

    You know the melting point for ice is O*C. So the temp difference will be 42. add 273 to convert into Kelvin (Specific heat is given in K unit)

    Mass x (temp difference + 273) x C where C is the specific heat capacity!

    1) Earth wire will make the casing live? LAst 2 are non-sense LMAO, and the first one can't be because eearth wire is at the wrong place, fuse won't blow. 2) Earth is always green as it is, and live brown. 3) They asked the electron flow, its always from -ve to +ve, and electron carries a -ve...

    Dudes, Why change *C to K ? The change in temp would still remain same!

    -_- Silly me, shlda asked the explanation before telling the right answer... Well the reason is, in a circular motion speed is constant (fact) but the direction changes! So acceleration can not be zero. It changes because velocity changes (cycle changes direction as it turns). The resultant...
