True or False Statements About Electrical Conductivity

1) Electrical conductivity of a body depends upon its atomic constitution. - True. The electrical conductivity of a material depends on its atomic constitution. Materials with free electrons in their atomic structure are good conductors of electricity, while those without free electrons are insulators. [[1 #1]]

2) There is no difference in the conducting ability of various substances. - False. There is a significant difference in the conducting ability of various substances. Conductors, such as metals, have high conducting ability, while insulators, like rubber or glass, have very low conducting ability. [[1 #1]]

3) The longer the wire is the weaker its opposition is. - False. The longer the wire, the greater its opposition to the flow of electricity. This is due to the increased resistance in the longer wire, which weakens the flow of current. [[1 #1]]

4) The kind of the insulating material depends upon the purpose it is meant for. - True. The choice of insulating material depends on the specific purpose it is meant for. Different insulating materials are used based on factors such as temperature, voltage, and environmental conditions. [[1 #1]]

5) Conductors are substances through which electricity is easily transmitted. - True. Conductors are materials through which electric current can easily flow due to the presence of free electrons that can move through the material. [[1 #1]]

6) Insulators do not allow the electric current to flow freely. - True. Insulators are materials that do not allow electric current to flow freely. They have very high resistance and prevent the flow of electricity. [[1 #1]]

In summary, the electrical conductivity of a material depends on its atomic constitution, with conductors allowing electricity to flow easily and insulators preventing the flow of electric current. The conducting ability of substances varies, and the length of a wire affects its opposition to the flow of electricity. Additionally, the choice of insulating material depends on its intended purpose.
