Answer to relevant QuestionsSketch the following complete circuits, using the symbols shown in Learn by Drawing 17.1: (a) Two ideal 6.0- V batteries in series wired to a capacitor followed by a resistor; (b) Two ideal 12.0- V batteries in parallel, ...(a) Three 1.5-V batteries are connected in series. What is the total voltage of the combination? (b) What would be the total voltage if the cells were connected in parallel? What is the emf of a battery with a 0.15-Ω internal resistance if the battery delivers 1.5 A to an externally connected 5.0-Ω resistor? The wire in a heating element of an electric stove burner has a 0.75-m effective length and a 2.0 x 10-6 ∙ m2 cross-sectional area. (a) If the wire is made of iron and operates at 380oC, what is its operating resistance? ...At 20 oC, a silicon rod of uniform cross-section is connected to a battery with a terminal voltage of 6.0 V and a 0.50-A current results. The temperature of the rod is then increased to 25 oC. (a) What is its new ...
