1. The problem statement, all variables and given/known data [PLAIN]http://img186.imageshack.us/img186/6260/physicsquestion.jpg [Broken] 2. Relevant equations Not sure...? 3. The attempt at a solution I believe the answer should be A or B. I'm thinking the live and earth wires will form a complete circuit. Since there is very low resistance, a huge current will be drawn, breaking the fuse. ...but it could be B since earth wire is attached to metal case & now the earth wire is connected to the live wire? ...? Thanks in advance!
