Question

Can you apply ohm’s law to a circuit which has an insulator? Is Ohm’s law applicable

for all materials? but they say that even insulators can be made as conductor with appropriate temperature and other stuff? explain it please​

Answer 1

Answer:

yes

Explanation:

it is applicable in certain temperatures conductors become super conductors and insulator becomes conductor for a while so ohms law is applicable

pls mark as brainliest

Answer 2

Explanation:

Ohm's law is proposed based on some observations only. There are many substances that does not obey the Ohm's law, even conductors (sometimes).

For example, you take the case of an incandescent bulb, the filament is made of a metal tungsten. This produces light when the current causes a heating effect and inturn produces a change in temperature.

This causes the lighting effect.

Here if you closely observe, one will notice that the change in temperature can cause a change in the resistance which will make the V-I graph a curve.

Now in order to convert an insulator into a conductor (which is practically a difficult process) can also be done by doping.

Silicon is not a good conductor as such. But when you dope it using a group 13 or group 15 elements, it is used as a semiconductor........

Those substances that obey Ohm's law are called ohmic substances and those that do not obey the Ohm's law are called non ohmic substances.....

hope it helps........
