= 4. Design an Ayrton shunt for a meter movement with internal resist- ance R=2,500 and full-scale deflection current Isa 50 μA to provide current ranges of 50 μA, 100 μA, 500 μA, 10 mA, and 100 mA. (a) Calculate the resistances of the Ayrton shunt components. (b) Draw the schematic diagram, including the switching arrangement, for this multirange dc ammeter.
