Circuit Design & Troubleshooting

📋 What it is

Designing a circuit means planning the path; troubleshooting means finding the break methodically.

🗣️ Coach says

Designing a circuit is planning: what power, what components, in what arrangement, to do the job safely. Troubleshooting is the reverse — when it fails, you check systematically (power? complete loop? component working?) rather than randomly. Both are careful, step-by-step reasoning.

🧠 Memory hook

Design = plan the path & components. Troubleshoot = check power → loop → component, in order.

Why do electricians make great detectives?
They're always finding faults in the circuit!

😲 Whoa!

Engineers use a "multimeter" to hunt faults — by measuring voltage step-by-step along a circuit, they can pinpoint exactly where the current stops flowing.

✅ Quick check: What’s a systematic way to find why a circuit isn’t working?

Say your answer out loud first — then reveal.

🧪 Try it! (2 minutes)

Draw a circuit, then imagine one fault; describe how you’d test to find it step by step.

🤸 Brain break: Trace-it: run a finger around an imagined loop and "stop" where the break is.
