Question
It is dangerous to connect the switch in the neutral wire. Explain your answer.
Solution
Even when the switch is turned off, the appliance's live wire remains connected to the high potential; however, no current flows through it due to the complete or broken return path. No one should attempt to fix the appliance at this time, since touching the live wire could cause a fatal shock as current flows through the body.
