(20%) Problem 1: Standard automobile batteries have six lead-acid cells in series, creating a total emf...
(17%) Problem 4: An electronic toy is powered by three 1.58-V alkaline cells, each with an internal resistance of 0.01852, and a 1.53-V carbon-zinc dry cell, whose internal resistance is 0.125 0. All four cells are connected in series as part of a single-loop circuit. The resistance of the rest of the circuit is 7.8 2. A 33% Part (a) What current, I. in amperes, flows through the toy's circuit? > A 33% Part (b) How much power. P, in...
