Req 10 — Choose Your Circuit Projects
10.
Do TWO of the following:
You must choose exactly two project options for this requirement. This page helps you compare them before you start buying materials or building anything. Some options focus on basic circuits, some focus on control devices, and some help you visualize how current behaves in real systems.
Your Options
- Req 10a — Battery, Switch, and Load: Build the most basic complete circuit using a battery, switch, and buzzer, bell, or light. You will learn how current flows only when the path is closed.
- Req 10b — Simple Electric Motor: Make a small motor and watch electricity turn into spinning motion. You will see electromagnetism doing real work.
- Req 10c — Build a Rheostat: Make a variable resistor and show how changing resistance changes current. This option is great for understanding control rather than just on/off behavior.
- Req 10d — Single-Pole, Double-Throw Switch: Build a switch that sends current down one of two paths. You will learn how circuits are routed and selected.
- Req 10e — How a 3-Way Switch Works: Explain one of the most useful real-home lighting circuits. This option is more about understanding wiring logic than building a battery project.
- Req 10f — Series vs. Parallel Circuits: Build the same two-light setup in two different ways and compare the results. You will learn one of the most important ideas in all of circuit design.
How to Choose
Picking your two projects
Think about materials, difficulty, and what you want to learn
- Simplest starting point: 10a and 10f usually need the fewest specialized parts.
- Best for motion and magnetism: 10b connects nicely to Req 3 — Build an Electromagnet.
- Best for understanding circuit control: 10c and 10d teach how changing resistance or switching paths affects behavior.
- Best for real-home wiring ideas: 10e and 10f connect most directly to household lighting circuits.
- What you gain: 10a teaches the complete-circuit idea, 10b teaches energy conversion, 10c teaches resistance control, 10d teaches switching logic, 10e teaches practical lighting control, and 10f teaches circuit comparison.
