Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

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
