Required by
- Computing an RC time constant and using the 63% and 5τ rules for delays and debouncing required
- Computing power with P = VI and checking it against a part's rating required
- Finding equivalent resistance, and the current and voltage of each part, in series and parallel required
- Measuring voltage, current, resistance and continuity safely with a multimeter required
- Using a pull-up or pull-down resistor to give an input a defined level required
