Capacitor and Its Working Investigatory Project PDF Class 12 Introduction A capacitor is an electronic component used to store electrical energy temporarily in an electric field. It consists of two conductive plates separated by an insulating material called a dielectric. When a voltage difference is applied across the plates, electric charge accumulates on them, creating an …

Moving Coil Galvanometer Investigatory Project PDF Class 12 Introduction A galvanometer is an electromechanical instrument for detecting and indicating electric current. A galvanometer works as an actuator, by producing a rotary deflection (of a “pointer”), in response to electric current flowing through a coil in a constant magnetic field. Early galvanometers were not calibrated, but …
