The ammeter on a switchboard, scaled 0-300A is accidentally damaged. The associated shunt is marked 300A, 150mV. A small ammeter, scaled 0-1A with a resistance of 0.12Ω, is available, and the possibility of using this is considered. Find if such an arrangement is possible, and if so, how it could be achieved using surplus resistors which are also available.
