its H2S hydrogen sulfide and i am afraid that two direction movement is right because the kettle runs on ac as said by Osaid Zahid. In ac, electrons move to and fro :confused: and plz to be noted ac and dc is in the syllabus of chemistry saw questions in past pprs in ac and dc

can u tell me which year? don't remember seeing it.

i

it wasnt really abt electricity conduction,was it? I think heating element was in the act....as the metal was heated up electons moved in both direction for the transfer of heat.....as we stdy in phy heat is transferred by atoms' vibrations as well as random movement of electrons......so it has to b right or???
But than y did they mention "electric kettle" ... From our knowledge of chemistry only, v were supposed to know that electrons in a circuit move in one direction only
