Earth wire is always to prevent from electric shock when metal case comes in live wire, in that case current flow to earth and it prevents electric current pass through human body

## Ans 2:

the answer should be b because the earth wire should be connected to the metal case. Current caring wire should be connected with the fuse.

I think the answer should be B - if earth wire is connected to the fuse (which will burn out after a certain threshold of current passes thru' it) , it will not prevent a shock.

The answer is B as metal case is only conductor and if fuse is connected it would be blown off

C should be correct as when V increases U and T will also increase and when T increases then S will also increase so S will have the greatest population and U will be second populated the population of T will go as S will eat T but there is no one to eat U so S is the highest and then U (is the second highest)
