• Use the simulation to answer to the questions depending on the group that you are assigned to. • Write the answers in your notebook. Explorers 1. Construct an electric circuit. Investigators 1. Construct an electric circuit and add to the circuit a resistor. 2. Add a resistor to your circuit. 3. What happened to the electric current when the resistor was added? Explain. Use the following keywords to explain: resistor, flow of current, decrease. 2.Explain how the resistor affected the electric current? 3.Click on the advanced option. Increase the wire resistivity. What do you notice in terms of the flow of the current? Explain. Researchers 1. Construct an electric circuit and add a resistor to the circuit. Click on advanced options and increase the resistivity of the wires. 2. What is the role of a resistor in an electric circuit? 3. When you increase the resistivity of the wires what did you notice in terms of the flow of electric current and lamp brightness? 4. What happens to the electrical energy flowing through the resistor? Is It transformed to another energy form? Explain.
