I'm not sure how safe this would be, but here's how I would do it: start with a small lightbulb (Barely larger than the tip of your thumb) a D battery, a plastic cup (A known insulator) and some pieces of insulated copper wire with the tips exposed. Use electrical tape to attach one wire to the posative end of the battery, then to the inside of the empty cup. Attach another wire to the negative end. Touch both wires to the lightbulb, to make sure the circut works. (You may have to mess around with the placement of the wires) If it lights up, then attach another piece of wire to the place on the lightbulb that the positive end was when the light was lit. attach the other end to the cup, on the other side from the one connected to the battery. Then attach the negative wire to the bulb where it worked. Fill up the cup. When it is touching both ends, the light will light up if it is a conductor, and stay dark if it is an insulator. I am going to write the answer next, so if you don't want it, don't read ahead. Water is a conductor.
Gold is an excellent conductor
An apple would be considered an insulator because it does not conduct electricity. The high water content and lack of metals in an apple make it a poor conductor of electricity.
Wood in itself is an insulator. But when wet, the water particles can conduct electricity.. Hence wet wood will be a conductor, although not a very good conductor, since the current passes only through a very small area
A rod can be either a conductor or an insulator, depending on its material properties. For example, a metal rod would act as a conductor, allowing electricity to flow through it easily. In contrast, a wooden rod would be an insulator, preventing the flow of electricity.
a insulator, because electrical cannot be transeverd.
Pure water is a insulator, however if there are ions in the water it becomes an excellent conductor.
An insulator or neither. The water inside of the sponge is what would conduct electricity.
Gold is an excellent conductor
A metal spoon would be a conductor, but a plastic one would be an insulator.🍴
A tooth pick is an insulator. A conductor would be metal.
The metal part itself would be a conductor in theory but the handle would be an insulator as it is usually rubber or plastic.
An apple would be considered an insulator because it does not conduct electricity. The high water content and lack of metals in an apple make it a poor conductor of electricity.
It depends. Pure water do not conduct electric current; on the other hand, we consider tap and river water as a conductor because of the ions of the decomposed materials in the water. Water transmits electricity, heat, and sound very well, so it is a conductor. An insulator would not transmit electricity, heat, or sound well.
Wood in itself is an insulator. But when wet, the water particles can conduct electricity.. Hence wet wood will be a conductor, although not a very good conductor, since the current passes only through a very small area
it would be a conductor, as most metal conducts electricity.
A frying pan would be a Conductor :)
Copper is a very efficient conductor
