Detailed Solution
Download Solution PDFसही उत्तर विकल्प 3):(56 Ω) है।
संकल्पना:
दो प्रतिरोधक R1 और R2 श्रेणी में जुड़े होने पर Req = R1 + R2 Ω
दो प्रतिरोधक R1 और R2 समानांतर रूप से में जुड़े होने पर Req = ( \(1\over R_1\) + \(1 \over R_2\))-1 Ω
गणना:
दिया गया है
परिपथ में 52 Ω और 28 Ω प्रतिरोध श्रेणी में हैं इसलिए Rt = 52 +28 = 80 Ω
80 Ω और 20 Ω समानांतर हैं इसलिए Rt1 = ( \(1 \over 80\) + \(1 \over 20\))-1 = 16 Ω
अब
15 Ω, 16 Ω, 25 Ω प्रतिरोध श्रेणी में संयोजित हैं इसलिए Req = 15 +16 + 25 = 56 Ω
