Two resistors R 1 and R 2 may be connected either in series or in parallel across
Question:
Two resistors R1 and R2 may be connected either in series or in parallel across an ideal battery with emf ?. We desire the rate of energy dissipation of the parallel combination to be five times that of the series combination. If Rl = 100?, what are the
