1. A moving coil voltmeter with a resistance of 150ohms gives a full scale deflection with a potential difference of 241 mV. The coil has an effective depth of 100mm and a width of 145mm. The permanent magnetic field has the flux of 20m Web with an area of 3mm, and 100mm. Controlling torque exerted by the spring is 451103 Newton-meter. Calculate the number of turns in the moving coil, and also calculate the deflection of the pointer. [1.5M]
