A moving coil voltmeter with a resistance of 150 ohms gives a full scale deflection with a potential difference of 100 mV. The coil has an effective depth of 100 mm and a width of 145 mm. The permanent magnetic field has the flux of 45 mWeb with an area of 3mm, and 50 mm. Controlling torque exerted by the spring is 50 x 10-6 Newton-meter. Calculate the number of turns in the moving coil, and also calculate the deflection of the pointer k=2*10-6
