वायर कुंडलीत प्रतिरोधक:

F2 S.B 11.9.20 Pallavi D 19

यामध्ये मेटलकोअरभोवती एक धातूची तार वळण घेत आहे. प्रतिकारासाठी धातूची तार वापरली जाते आणि मेटलकोरचा वापर इन्सुलेटर म्हणून केला जातो.

वायरचा प्रतिकार खालील मिश्रधातूंनी बनलेला असतो:

  • कॉपर-निकेल - मॅंगनीजला मॅंगॅनिन म्हणतात.
  • कॉपर-निकेलला युरेका किंवा कॉन्स्टंटन म्हणतात

इन्सुलेटर सामग्री सिरेमिक, प्लास्टिक आणि काच आहेत

टीप: टंगस्टनचा वापर बल्बचे फिलामेंट बनवण्यासाठी केला जातो कारण त्यात वितळण्याचे बिंदू खूप जास्त असतात.
