(6%) Problem 11: An electronic toy is powered by three 1.58-V alkaline cells, each with an internal resistance of 0.018 Q and a 1.53-V carbon-zinc dry cell, whose internal resistance is 0.085 2. All four cells are connected in series as part of a single-loop circuit. The resistance of the rest of the circuit is 11.325 Ω. 33% Part (a) What current. I in amperes, flows through the toy's circuit?

That results in a reduced power of only 0.500 W supplied to the toy. What is the internal resistance, n2 failing in ohms of the failed dry cell?
