Some materials are classified as poor conductor of electricity they allow electricity to pass under certain conditions. Explain with examples
Answers
Answer:
Some substances are poor conductors because they do not possess freely moving ions but they conduct electricity in their aqeous solution beacuse their ions become free to move when dissolved in water. Common example of such substances is NaCl which is commnly called table salt
Answer:
Explanation:Some materials are classified as poor conductors which doesn't mean that electricity cannot be passed through it.
When an electric current is passed through a insulator, the current actually passes through it but it is very weak
A material can become a good conductor by certain condition
Ex:- GASES(hydrogen)
1) When the gas is stored at a low pressure (0.01-0.001mm of mercury)
2)When a very high voltage is applied through the gas (more than 10,000 volts)
