Question

2
a) Wooden scale b) measuring tape
Which of the following is a conductor of electric current?
a) Wooden toy b) Iron nail
c) Plastic pen
d) Rubber eraser​

Answer 1

Answer:

Well electricity is really just due to a flow of electrons in a material. So to be a good conductor, a material needs to allow electrons to move freely.

Metals have lots of 'free' electrons (very loosely bound electrons), and so metals can support a large current, without needing a high voltage to move the electrons.

Wood does not contain free electrons in its valence region so it can't pass the charge i.e. electricity and hence is a bad conductor.

Thus bulb glow will not glow.

Hence the correct option is A.
