Purpose and Features: The simulation appears to allow users to construct and analyze various circuit configurations involving light bulbs (A, B, C, D) and a battery. The second source provides specific "Link" examples with predefined parameters: Link 1: Voltage of Battery = 15V, Bulbs A, B, C, D with Power, Voltage, warmup time, cooldown time = 9, 9, 10ms, 10ms. The comment suggests that the 10 millisecond duration is chosen "to avoid the effects of warmup and cooldown." Link 2: Voltage of Battery = 15V, Bulbs A, B, C, D with Power, Voltage, warmup time, cooldown time = 9, 9, 1, 1. This configuration is suggested to be "more realistic maybe JC students to appreciate that the big ideas in Physics of time dependent states." This implies the simulation can be adjusted to demonstrate both idealized and more complex, time-dependent electrical behaviors. The "simulation speed" is set to "maximum so that novice students don't have to struggle with the effects of warmup and cooldown," further indicating a focus on accessibility for beginners. User Interaction: The text mentions the possibility to "click the 2 way switch instead of dragging it to position," indicating interactive elements within the simulation. Desired Circuit Configurations: A significant portion of the second source lists various "Desired Circuit" configurations, including individual lamps, lamps in series (AB, AC, AD, BC, BD, CD, ABC, ABD, BCD, ABCD), and lamps in parallel (AB, AC, AD, BC, BD, CD, ABC, ABD, BCD, ABCD), as well as combinations of series and parallel circuits (e.g., "ABC series & D in parallel with them"). Each desired circuit is represented by a sequence of numbers (potentially node connections or switch positions), suggesting a way to define and load specific circuit arrangements within the simulation. For example, "Desired Circuit Lamp C alone" is represented by "1 2 3 4 5 6 7 8 9 10 11 1 1 1 1 1 1 1 1 1 1 1 11,4,6, it is possible to click the 2 way switch instead of dragging it to position".

The Foutan Board is a JavaScript HTML5 applet simulation model focused on practical electricity, allowing users to interact with circuit configurations involving multiple light bulbs and switches. Key Concepts Circuit Simulation: The Foutan Board is a virtual environment that models the behavior of electrical circuits. Series Circuits: Components in a series circuit are connected end-to-end, so the same current flows through each component. If one component fails, the entire circuit is broken. Parallel Circuits: Components in a parallel circuit are connected across each other, providing multiple paths for the current. If one component fails, the other branches of the circuit can still function. Voltage: The electrical potential difference or pressure that drives the current through a circuit. In this simulation, the battery voltage is set at 15V. Current: The flow of electrical charge through a circuit. Power: The rate at which electrical energy is transferred in a circuit. The power of the bulbs is mentioned (9W or 1W) and can affect their brightness. Switches: Devices that can open or close an electrical circuit, controlling the flow of current. The Foutan Board interface includes a two-way switch. Light Bulb Behavior: The simulation models the behavior of light bulbs in different circuit configurations, including potential effects of warmup and cooldown times (though these are often minimized for simplicity). Open Educational Resource (OER): The Foutan Board is released under an open license, making it freely available for educational use and modification.

Describe one specific user interaction mentioned in the excerpts regarding the Foutan Board interface. What were some of the identified shortcomings of a previous circuit simulator that the Foutan Board aimed to address? Where can a user find the source code for the original circuit simulator upon which the Foutan Board is based? How can the Foutan Board simulation be embedded into a webpage? Quiz Answer Key The primary purpose of the Foutan Board simulation is to model and demonstrate practical electricity concepts through interactive circuit configurations involving light bulbs and switches. It allows users to observe how different arrangements affect the behavior of the circuit. In a series circuit, components are connected sequentially along a single path, meaning the same current flows through each. In contrast, a parallel circuit provides multiple pathways for the current, with each component connected independently across the voltage source. According to the provided links within the excerpts, the voltage of the battery used in some configurations of the Foutan Board simulation is set at 15V. This value influences the current and power in the circuit. Warmup and cooldown times for the light bulbs are sometimes set to a small value like 10 milliseconds to avoid the complicating effects of these transient states, especially for novice students. This allows users to focus on the fundamental principles of circuit behavior in a steady state. The Foutan Board is released under the GNU General Public License, which is a type of open license. This typically means that users have the freedom to use, distribute, and modify the software, often with the requirement that any derivative works are also released under a similar open license. The Foutan Board simulation is built using JavaScript for its interactive functionality and HTML5 for the structure and presentation of the applet within a web browser. It is a JavaScript HTML5 applet simulation model. The excerpts mention that in the Foutan Board interface, it is possible to interact with the two-way switch by clicking it instead of dragging it to a desired position (specifically noted in relation to configuring Lamp C alone). Previous circuit simulators were identified as not being appealing or user-friendly for students. Additionally, the brightness of bulbs in those simulators was not easily comparable, which hindered visual understanding of circuit behavior.
