Notes Chapter 14. Chemical Effects of Electric Current - Good conductors and Bad conductors | Class 8 Science - Toppers Study

Conductors: All materials are conductors if the electricity current passes through them.

चालक : सभी पदार्थ चालक होते है यदि उनसे विद्युत धारा प्रवाहित होती है |

Types of conductors:

There are three types of conductors:

(i) Good conductors :

(ii) Bad conductors or Poor conductors

(iii) Super conductors

चालक के प्रकार :

चालक तीन प्रकार के होते है :

(i) सुचालक

(ii) कुचालक

(iii) अतिचालक

(i) Good conductors : The materials, which allow electric current to pass through them very easily, are called good conductors of electricity.

Examples: Copper, Iron, Alluminium etc.

(i) सुचालक : वे पदार्थ जो अपने से होकर विद्युत धारा को आसानी से गुजरने देते हैं, विद्युत के सुचालक कहलाते हैं |

उदाहरण : ताँबा, लोहा और एल्युमिनियम इत्यादि |

(ii) Bad conductors: The materials, which do not allow electric current to pass through them easily, are called poor conductors of electricity.

Examples: Wood, Led, Rubber एंड Plastics etc.

(ii) कुचालक : वे पदार्थ

जो अपने से होकर विद्युत धारा को आसानी से गुजरने नहीं देते है वे पदार्थ विद्युत के कुचालक कहलाते हैं |

उदाहरण : लकड़ी, प्लास्टिक, रबड़ और शीशा इत्यादि |

(iii) Super conductors : The materials which has zero resistivity against electric current or allow fully through them, are called super conductors of electricity.

Example: Gold and Silver etc.

(iii) अतिचालक : वे पदार्थ जो विद्युत धारा का बिल्कुल विरोध नहीं करते आसानी से गुजरने देते हैं अतिचालक कहलाते है |

जैसे - सोना और चाँदी इत्यादि |
