Given three batteries with voltages of 1.0 V, 3.0 V, and 12 V, what are the minimum and maximum voltages that could be achieved by connecting them in series?
Answer to relevant QuestionsIf the heater in Exercise 39 is efficient, how long would it take to heat 50 gal of water from 20oC to 80oC? (a) What is the resistance of an immersion-type heating coil if it is to generate 15 kJ of heat per minute when it is connected to a 120-V source? (b) What would the coil’s resistance have to be if instead 10 kJ of heat ...A 20-Ω resistor is connected to four 1.5-V batteries. What is the joule heat loss per minute in the resistor if the batteries are connected (a) In series and (b) In parallel? Two pieces of aluminum and copper wire are identical in length and diameter. At some temperature, one of the wires will have the same resistance that the other has at 20oC. (a) What is that temperature? (b) If the two ...In a country setting it is common to see a hawk sitting on a single high-voltage electric power line searching for a roadkill meal (Fig. 17.19). To understand why this bird isn’t electrocuted, let’s do a ballpark ...
