A galvanometer havings a coil resistance of 60 $\Omega $ shows full scale deflection when a current of 1.0 amp passes through it. It can be converted into an ammeter to read currents upto 5.0 amp by
putting in series a resistance of 15 $\Omega $
putting in series a resistance of 240 $\Omega $
putting in parallel a resistance of 15 $\Omega $
putting in parallel a resistance of 240 $\Omega $
