Name: Aaron Banks Section: Thursday PRELAB: A MODEL FOR CIRCUITS I: ELECTRIC CURRENT 1. What do you predict for the rankings of the brightness of bulbs A, B, and C in Figure 2-1? A>B>C A being the brightest
2. How do you predict that changing the direction of the current by reversing the connections to the battery in Figure 2-1 would change the rankings in (1)? I don’t think it will change at all. The brightness should be the same in diagram b and diagram a it should also stay the same.
3. How will you compare the currents in the circuits in Figure 2-1 experimentally? What equipment will you use? Take the current left of the bulb and right of the bulb in figure a and take the current left and right of each bulb
