Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf Îĩ. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 Ī, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 â 103 s. given that the charge of an electron is 1.6022 â 10â19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
