Electric current and circuits

This CTET Paper 2 chapter builds Electric current and circuits for future Classes VI-VIII science teachers: cell and battery, bulb and switch, conductors and insulators, simple open and closed circuits, a light series-parallel contrast, heating and magnetic effects overview, and safety ideas like short circuit, fuse and earthing. Teacher voice focuses on open-versus-closed traps, TLM and hard CTET stems. Magnets stay a one-line sibling only.
