So here the question is that which is a good insulator of electricity.
00:04
So we are given the four options and out of this we have to find out the good insulator.
00:08
First is aluminum foil, second is copper wire, third is gold wire and the fourth is plastic.
00:24
We have to find out the insulator from here.
00:27
So firstly we need to understand basically what a insulator is.
00:31
So insulator is a material that does not allow electricity to pass or we can say that to flow through it easily.
00:50
So it is opposite to that of a conductor which allow electricity to flow through it easily.
00:57
So from the option we are considering first about the aluminum foil.
01:01
So aluminum foil, aluminum is basically a good conductor of electricity.
01:05
So it is not a good insulator...
