Мавзу: G‘altakning induktivligini, to‘la kuchlanish va tok orasidagi faza siljishini hamda muhitning magnit singdiruvchanligini aniqlash

Ishni bajarish tartibi

• 
  Tajriba ishining yo'riqnomasi bilan tanishib bo'lgach, 8- rasmda keltirilgan elektr zanjirini tuzing va uning to'g'riligini o'qituvchiga tekshirtiring. Qurilmani ishga tushirish uchun o'qituvchidan ruxsat oling.
  
• 
  Qurilma tarkibidagi tok manbaini tok tarmog'iga ulang.
  
• 
  To'g'ri ulangan diodning volt-amper xarakteristikasini olib bo'lgach qurilmani o’chiring
  
• 
  Diodni tok manbaiga teskari yo'nalishda ulang
  
• 
  Diodga berilayotgan kuchlanishning turli qiymatlarida undan oqayotgan teskari tokning qiymatlarini mikroampermetr yordamida qayd eting.
  
• 
  Olingan natijalar asosida quyidagi jadvalni to'ldiring:
  
• 
  Tajriba natijalari asosida diodning volt-amper xarakteristikasini grafigini chizing.
