Electricity is useful but can hurt or kill. Home sockets in India give about 230 V — never use them for projects, never poke anything into a socket, and never touch switches with wet hands, because water carries current. Stay away from fallen wires, electric poles and transformers. Build only with small battery cells (up to about 9 V) and always with a trusted adult nearby.
