a galavano meter having resistance of 50 ohm gives full scale deflection for a current of 0.05 A the length in the meter of a resistance wire of area of croos section 0.00297 that can be used to convert the galavanometer in to ammeter which can read maximum 5A current is(specific resistance of wire 5*10^-7)
