Galvanometer plane transmission grating is the best example of Suitable for testing fan andA Galvanometer is an instrument used to detect and measure small electric currents by deflecting a needle or pointer in response to the current flow. Key features of a Galvanometer: Consists of a coil of wire suspended in a magnetic field. When current passes through the coil, it experiences a torque causing the needle to move. The needle's deflection is proportional to the current magnitude. Used in laboratories and electrical measurements to detect
