39. A 1-phase transformer has 400 primary and 1000 secondary turns. The net cross-sectional area of the core is 60 cm 2 . If the primary winding is connected to a 50-Hz supply at 500V, find the voltage induced in the secondary winding. 1-फेज परिणामित्र में 400 प्राथमिक और 1000 द्वितीयक वर्तन हैं। कोर के शुद्ध अनुप्रस्थ-काट का क्षेत्रफल 60 cm 2 है। यदि प्राथमिक कुंडलन 500V पर 50-Hz की आपूर्ति से जुड़ा है, तो द्वितीयक कुंडलन (वाइंडिंग) में प्रेरित वोल्टेज ज्ञात कीजिए।
(A) 12.25 V
(B) 1320 V
(C) 1250 V
(D) 13.20 V
51. A 3300/250 V, 50 Hz single phase transformer designed to carry 70 turns of low voltage winding on a core of 125 cm effective cross section. What is the number of Turn on the high voltage winding? एक 3300/250 वॉल्ट, 50 हर्ट्ज सिंगल फेज ट्रांसफार्मर जो कि 125 सेमी प्रभावी क्रॉस सेक्शन कोर पर और 70 टर्न कम वोल्टेज वाईंडिंग को चालू करने के लिए बनाया गया है। उच्च वोल्टेज वाईंडिंग पर चक्र की संख्या क्या है?
(A) 663
(B) 924
(C) 1848
(D) 462
57. What will be the turn ratio of a transformer which converts 1500 V to 30 V? उस परिणामित्र का फेरा अनुपात क्या होगा जो 1500 V से 30V का रूपांतरण करता है?
(A) 1 : 25
(B) 25:1
(C) 50 : 1
(D) 1 : 50
00. A transformer having a primary coil of 100 turns and a secondary coil of 2000 turns has 12V across its primary. What is output voltage? एक ट्रांसफॉर्मर जिसका एक प्राथमिक क्वाइल 100 टर्न का और एक माध्यमिक क्वाइल 2000 टर्न का है, इसमें 12V इसके प्राथमिक से जुड़ा हुआ है। आउटपुट वोल्टेज क्या है?
(A) 130 V
(B) 170 V
(C) 200 V
(D) 240 V
44. The maximum flux density in the core of a 250/3000-V 50Hz single phase transformer is 1.2 Wb/m2. If E.M. f./turn is 8V, then what will be the number of primary (N) and secondary (N) turns? एक 250/3000-V 50Hz सिंगल फेज ट्रांसफॉर्मर के कोर में अधिकतम प्रवाह (फ्लक्स) घनत्व 1.2 Wb/m2 है। यदि ई.एम. एफ./ टर्न 8V है, तो प्राइमरी (N) और सेकेंडरी (N) टर्न की संख्या कितनी होगी?
(A) N1 = 30, N2 = 365
(B) N1 = 30, N2 = 305
(C) N1 = 370, N2 =30
(D) N1 = 30, N2 = 375
