Given a d'Arsonval meter movement with a full scale (FS) current of 50mA and a resistance of 2ohms, determine the value of the shunt that should be used to construct an ammeter (AM) with a sensitivity of 200mA FS. Show your work with a complete circuit diagram and mark on it the values of all components, including the shunt after you've calculated its value.
