Please help me with this question Share with your friends Share 0 Rohit Babu answered this Dear Student, The figure is redrawn as.. Let C be the capacitance of the infinite ladder between X and Y . The ladder is infinite,so when we add a combination of two capacitors (1μF and 2μF) across X and Y it won't change the total capacitance C.Now C and 2μF capacitor are in series.Ct=2×C2+CCt is in series with 1μF⇒Total capcitance is,C=Ct+1⇒C=1+2×C2+C=2+C+2C2+C⇒2C+C2=2+3C⇒C2-C-2=0⇒C=2 or -1As capacitance can't be negative C=2μFRegards.. 0 View Full Answer
