Lesson 22: Learning the Language for DC Circuits

Goal Today you are going to begin learning the language for representing circuits and build analogies to relate Circuits to real world concepts. Instructions Complete each activity on this lesson and record your responses. Be sure to answer prompts completely and fully, or this assignment may be marked as "incomplete" and returned to you for revisions. Review Head over to our Circuit Simulation to study how we can represent circuits with diagrams here.-Click "Intro"-Pull out one battery, one wire, one lightbulb, and one switch-Connect all four so that your lightbulb turns on! When you click the switch, what do you notice happen to the circuit? Does this make sense with what we learned in the last lesson about how to make a circuit? Explain. Drawing Circuit Diagrams Keeping the simulation open, locate the icon with the battery on the right and click the symbol to its right. It should look like the image below:This switches the simulation from the picture representation to its circuit diagram representation. Match the symbols On the image below, label which symbol is the battery and which symbol is the lightbulb lightbulb battery Reflect and Reason Construct a simple circuit with a battery and a lightbulb. You can use as many wires as you need. Switch between the Circuit Representation and Picture Representation.Sort the statements below as true and false. True To represent the battery in a circuit diagram, the long side indicates the positive end of the battery and the short side indicates the negative end of the battery. False To represent the battery in a circuit diagram, the short side indicates the positive end of the battery and the long side indicates the negative end of the battery. Did you know? There are more elements you can put into a circuit! These are known as resistors. Resistors convert the energy from the electrons into other forms of energy. Lightbulbs are examples of resistors that convert energy into light energy.The circuit diagram representation of a resistor is: Represent Use the symbols to draw a circuit for a battery, lightbulb, resistor, and a single wire. Make sure the diagram represents a circuit in which the bulb would light. The symbols needed are there as examples. Use the shape and drawing tools to create your circuit diagram. Represent Use the symbols to draw another circuit for a battery, lightbulb, resistor, and a single wire. Make sure the diagram represents a circuit in which the bulb would light. The symbols needed are there as examples. Use the shape and drawing tools to create your circuit diagram. Represent You see the following circuit. Represent it as a diagram: Observe and Explain - Multiple Light Bulbs Recreate the following circuit diagrams in the simulation. You should be looking at them in the picture representation view so that you can see the brightness of the bulbs. Try to fit all three on your screen at the same time so that you can compare them.Rank the brightness of the bulbs in each circuit by typing in their circuit letter below. Use <, >, or = to compare the brightness. Explain how you know.Brightest _. _. _ Dimmest In the brightest circuit, what do you observe about the flow of the electrons as they pass the lightbulb? Does this make sense? Explain. Now look at Circuit B, which bulb shines the brightest? What do you observe about the electron flow rate through each lightbulb? Now look at Circuit C, which bulb shines the brightest? What do you observe about the electron flow rate through each lightbulb? Based on your observations for the last two questions, do you think it matters which lightbulb is closer to from the battery? Explain. Observe and Explain - Multiple Batteries Make the following configurations in the circuit simulation:Rank the circuits in order of brightness by typing in their circuit letter below. Use <, >, or = to compare the brightness. Explain how you know. Use this format:Brightest _ _ _ Dimmest Change around the circuit. Does a longer wire change the brightness of the light bulb? Check your understanding Element A represents what in the following circuit? Resistor Battery Light Element B represents what in the circuit above? Resistor Battery Light Element C represents what in the above circuit? Resistor Battery Light Based on the image below, what should the circuit diagram look like? Which sentence is most likely true based on the patterns you observed? Adding batteries by connecting the positive side of one battery to the positive side of the next battery to a circuit will make the bulbs brighter because the electrons flow faster. Adding batteries by connecting the negative side of one battery to the positive side of the next battery to a circuit will make the bulbs brighter because the electrons flow faster. Adding batteries by connecting the negative side of one battery to the positive side of the next battery to a circuit will make the bulbs brighter because the electrons flow more slowly Adding batteries by connecting the positive side of one battery to the positive side of the next battery to a circuit will make the bulbs brighter because the electrons flow more slowly. When lights are connected in a circle right next to one another, which of the following is TRUE? (Assume the circuit is complete and the wire is connected to the other side of the light.) The light closest to the positive side of the battery is the brightest. The light closest to the negative side of the battery is the brightest. All of the lights have the same brightness. When lights are connected in a row (looks like a ladder) what is TRUE about their brightness? (When the circuit is complete and the wires are connected.) The light closest to the battery is the brightest The light farthest from the battery is the brightest They are all the same brightness Which of the two circuits would have a brighter lightbulb? How did you overcome a challenge with this assignment?
