Detailed Solution
Download Solution PDFसंकल्पना:
जेव्हा रोधक डेल्टामध्ये जोडलेले असतात, तेव्हा परिपथ खाली दर्शविल्याप्रमाणे असतो.
वापरली गेलेली ऊर्जा, \({W_{\rm{\Delta }}} = \frac{{3V_L^2}}{R}\)
जेव्हा रोधक तारेमध्ये जोडलेले असतात, तेव्हा खाली दर्शविल्याप्रमाणे परिपथ असते.
तारांकित चे डेल्टा रूपांतरण वापरून, परिपथ पुढीलप्रमाणे बनते.
वापरली गेलेली उर्जा, \({W_Y} = \frac{{3V_L^2}}{{3R}} = \frac{{V_L^2}}{R}\)
म्हणून, WΔ = 3WY
त्यामुळे तारांकित रचनेमध्ये तीन समान रोधकांद्वारे वापरली जाणारी उर्जा ही डेल्टा रचनेमध्ये वीज वापराच्या 1/3 पट आहे.
