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

    The concepts behind the direct relationship of battery cells and compass deflection are the same concepts that support the direct relationship of voltage difference and current included in Ohm’s Law. When we began gather data using Ohm’s Laws, the trend of current increasing as voltage increases made sense because Unit 2 Activity 3 taught me that flow rate increases when the number of battery cells increases.…

    The Working of Wires

    INTRODUCTION Electricity is usually invisible. Except for lightning and sparks, you never see it in daily life. However, light bulbs and a magnetic compass can show you when something electrical is happening. By observing their behavior and making a few assumptions, you can begin forming ideas about electricity. This type of thinking is called “building a model”. INVESTIGATION ONE: WHAT IS NEEDED TO LIGHT A BULB? 1.1 Activity: Lighting bulbs in a loop Insert three D-cells into the battery holder (as in Figure 1.1), and insert two ROUND bulbs (not long bulbs) into a pair of sockets. Use three wires to connect the sockets to each other and to the two “terminals” of the battery holder: 1) the spring inside the case near the red spot, and 2) the metal post on the outside of the case near the blue spot. The bulbs should light and be of similar brightness. The battery, bulbs and wires now form a “closed loop”.…
