Astudent is experimenting with a battery, three identical light bulbs, and some wire. first, she creates a circuit with the light bulbs in series, and next, in parallel, and observes the brightnesses of the bulbs for each circuit. she decides to analyze the total power from the battery for both circuits, assuming that the battery emf is e m f and the three bulbs each have constant resistance r. (for all symbolic answers, use the following as necessary: r and ℰ for e m ) what is the total power from the battery if the bulbs are connected in series? 2r find the equivalent resistance for the series combination, and apply the relationship among power, emf, and equivalent resistance
