1. they are enert noble gasses the don`t react with metel even high tempreture
2. becose they have low resistivety.low resisitivety inversaly propertio to low current in circuit.they also have good conductor
3.Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component
if u like comment thanks

Answer:
(i) Electric bulbs are usually filled with chemically inactive gases like nitrogen and argon because they are the gases which do not react even at high temperature.
(ii) Copper and aluminium wires are usually employed for electricity transmission because they have low resistivity and also are good conductors of electricity.
(iii) Fuses are always connected in series with the device so that if in any situation the high voltage of current is passed, the device can be protected.
