Question
(a) Design an Ayrton shunt to provide an ammeter with current ranges of 1A, 5A and 10A. A d'Arsonval movement with an internal resistance $R_m = 50\Omega$ and full scale deflection current of 1mA is used in the configuration of Fig. 1.
(b) Discuss the construction and working of a series and shunt type ohmmeter.
