Asimple circuit is used to light a bulb. what would happen if a wire were replaced with a material that does not conduct electricity?
a.
the light from the bulb would not change.
b.
there would be no light from the bulb.
c.
the light from the bulb would get brighter.
d.
the light from the bulb would get dimmer.

THERE WOULD BE NO LIGHT FROM THE BULB when the wire of simple circuit to light the bulb is replaced with non-conducting material of electricity.

Option B

Explanation:

Conducting materials has free electrons which are loosely held and moves through the material. When external power supply is connected, these electrons acquire energy and conduct current.

If the wire is replaced with non-conducting material like insulators, electrons are tightly held, they do not move freely and does not conduct electricity. This is the reason that there would be no light in the bulb when wire is replaced by non-conducting material.
