Question
1. Are the blue spheres moving through the circuit positive or negative charges? How can you tell?
2. What happens when you increase the resistance of the resistor? How does the current through the circuit, the speed of the blue spheres, the voltage across the battery, the temperature of the resistor, and the green particles in the resistor change? Why (or why not) does each of these change as they do?
