Question

give two reasons:
wires are used for electrical connection.

*this question is of chemistry

Answer 1

Both loads won’t get rated voltage (usually 230v) as voltage will be divided for two loads. Some loads won’t work if it is not getting rated voltageIn order to turn on your bulb you have to turn on your fan switch also. You can’t control a single load. Either turn on both bulb and fan or turn off both.If you turn on both bulb and fan. Bulb will not glow in its full brightness , fan won’t rotate its full speed.

Answer 2

Favorable Chemical Properties: The chemical properties of this metal go a great deal in making it an ideal element for making electrical wires. Copper’s favorable chemical properties make it resistant to abrasion and other bad effects that shorten the life of a wire. These wires can safely withstand adverse climatic conditions and thus last longer.
