Insulator is bad conductor of electricity so it not allow to pass current.

I know insulator is a bad conductor. But in question asking under "normal condition". I think answer is sc.

The answer may be semiconductor also why b/c in normal condition it doesn't allow to flow electrons. It allows electrons only when temp is critical temp & critical temp is not as a normal condition.

But at normal condition semiconductor work as an insulator the answer should b semiconductor I think n as temperature increases it work as conductor. So why the answer is insulator.

Insulator are materials that does not allow the passes of electricity. Why through them?

Insulator becomes conductive when temperature goes beyond break down level so at high voltage level current flows through it that called abnormal condition.

But a insulator not allow the flow of current then how it can.

Under Normal Condition, Semiconductors are also Behave Like Insulators. So the question is wrong I think.

In case of insulator free electrons are very less compared to conductor since. It won't carry current.

Under normal conditions semiconductor also doesn't allow current through it.
It needs an external energy source.
So, the insulator and semiconductor both will be correct.
