Q1. A moving coil PMMC has a coil of resistance 100 22 and a full-scale deflection current of 50 uA. This meter is to be used to operate (a) as a voltmeter with a full-scale deflection of 30 V; (b) as an ammeter with a full-scale deflection of 2 A. (i) Sketch the circuit diagram in each case, calculate the resistance of necessary components. (ii) What is the sensitivity of the voltmeter in (a)? (10 marks) (10 marks)
