Prediction 1-2: What do you predict will happen to the brightness of bulbs A, B, and C in Figure 2'1 if the battery is connected to the bulbs with its terminals reversed? Explain the reason(s) for your prediction. 2. Test your prediction. Reverse the terminals of the battery in each of your circuits. Question 1-2: What do you observe? Does this agree with your prediction? Did you make any false assumptions? Explain. Question 1-3: Can you tell anything about the direction of the current through the circuit by just looking at the brightness of the bulbs without knowing how the battery is hooked up? Explain. How does each bulb affect the current in a circuit? Does current get used up after passing through a bulb? How does the current in the two'bulb circuit compare to that in the single-bulb circuit? First make predictions and then observe experimentally. Prediction 1-3: What would you predict about the relative amount of current going through each bulb in Figures ana and b? Write down your predicted rankings of the currents through bulbs A, B, and C, and explain your reasoning
