Question
Download Solution PDFएक 230 V मोटर में 0.8 ओम का आर्मेचर परिपथ प्रतिरोध है। यदि पूर्ण भार आर्मेचर धारा 25 A है, तो आर्मेचर में प्रेरित पश्च EMF ज्ञात कीजिए।
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसही उत्तर विकल्प 1):(210 V) है
संकल्पना:
DC जनरेटर में, उत्पन्न emf निम्न द्वारा दिया जाता है
Eg = Vt + IaRa
DC मोटर में, पश्च emf निम्न द्वारा दिया जाता है
Eb = V – IaRa
जहाँ,
Ia आर्मेचर धारा है
Ra आर्मेचर प्रतिरोध है
गणना:
आर्मेचर प्रतिरोध (Ra) = 0.8 ohm
वोल्टेज (V) = 230 V
आर्मेचर धारा (Ia) = 25 A
Eb = V – IaRa = 230 – 25(0.8) = 230 - 20 = 210 V
