Chapter 27, Problem 86P
Two resistors R1 and R2 may be connected either in series or in parallel across an ideal battery with emf ℰ. We desire the rate of energy dissipation of the parallel combination to be five times that of the series combination. If R1 = 100 Ω, What are the (a) smaller and (b) larger of the two values of R2 that result in that dissipation rate?
