Question

1. Use the formulas for series and parallel equivalent resistances (H&H p. 5, Eqs. 1.3 and 1.4) to calculate the cquvalcut rsısiantTS 14, 1/? aud 14 Usung the l'oiaiaou แ1129 to İll.licate a parallel connection of two resistances, you should be able to see that R3- R(2R)R2 and if you were to keep adding additional resistors to the ladder, Rn+1-(2R)|Rn. Look carefully at your results: what do you guess Rio would be, roughly? (Don't work it out, just make a guess.) R2R R32R 2 R 2R (and so forth) 2. In the above problem, calculate (exactly) the resistance of an infinite ladder, Ro? (Hint: Root Ro)
