Last Monday, Ankush woke up late in the morning. So, he saw the time and suddenly realised that he had got late for an interview, which he was supposed to give after reaching the venue by the right time. Immediately, he turned ON the geyser but it did not work. He got more tensed, then he used an electric Iron rod through which he could get some boiled water for his bath. Actually, there was an earthing problem in the switch board which he was unaware of. He was barefoot and was just about to switch ON the electric iron rod but at the same he was stopped from doing so by one of his room partner living with him. It could be dangerous for Ankush.
(i) Explain in brief that what could be happened with Ankush, if he switched ON the electric iron rod (without wearing any slippers in his foot).
(ii) Mention the values showed by Ankush's friend.
