Electronics Questions to answer
Open prompts for revision or future project notes. Keep this list practical: questions should point to examples, measurements, or atomic notes worth making.
Concept checks
- When is an ideal-wire model good enough, and when do wire resistance, capacitance, or inductance matter?
- Why does a battery maintain a Voltage even when no steady Current flows?
- How should “ground” be chosen in a circuit with multiple supplies?
- What exactly changes across a resistor if Charge is conserved?
Problem-solving prompts
- Given a circuit, can I identify series parts by “same current” and parallel parts by “same voltage” before using formulas?
- Can I predict whether a component absorbs or supplies power using the passive sign convention?
- Can I estimate whether a resistor power rating is safe from , , or ?
Future notes to split out
- Kirchhoff’s circuit laws as their own note.
- Capacitors: charge storage, , and transient behaviour.
- Inductors: magnetic energy storage and current-change opposition.
- Diodes/LEDs: nonlinear current-voltage curves.
- Transistors as switches and amplifiers.
Mini lab ideas
- Measure the voltage divider made from two resistors and compare with calculation.
- Build an LED circuit and choose the current-limiting Resistance.
- Use a multimeter to verify that series current is shared but voltage drops split.
