This is untimed educational practice for one applied skill. It is not a clinical, diagnostic, employment, or professionally recognized assessment, it does not produce a score or credential, and for the judgement and safety families it is not a substitute for your employer's own policies, training, or legal duties.
| Item | Choice | Answer |
|---|---|---|
| electrical-reasoning-applied-s01-q01 | B | 3 A |
| electrical-reasoning-applied-s01-q02 | C | In parallel across the component, reading the potential difference across it |
| electrical-reasoning-applied-s01-q03 | A | 2300 W |
| electrical-reasoning-applied-s01-q04 | D | It halves |
| electrical-reasoning-applied-s01-q05 | C | It halves |
| electrical-reasoning-applied-s02-q01 | D | 18 ohm |
| electrical-reasoning-applied-s02-q02 | A | 3 ohm |
| electrical-reasoning-applied-s02-q03 | B | The current is the same at every point, and the supply voltage divides across the components |
| electrical-reasoning-applied-s02-q04 | C | The lamps are in series, so a break anywhere opens the only path |
| electrical-reasoning-applied-s02-q05 | A | It stays at the same brightness, because it still has the full 12 V across it |
| electrical-reasoning-applied-s03-q01 | C | A fuse |
| electrical-reasoning-applied-s03-q02 | B | It allows current to flow in one direction only |
| electrical-reasoning-applied-s03-q03 | D | A pair of two-way (single-pole double-throw) switches |
| electrical-reasoning-applied-s03-q04 | A | 12 V |
| electrical-reasoning-applied-s03-q05 | D | It blocks steady direct current, so the current in that branch falls to zero |
| electrical-reasoning-applied-s04-q01 | A | A short circuit inside the appliance drawing a very large current immediately |
| electrical-reasoning-applied-s04-q02 | D | A difference between the current in the line and neutral conductors, meaning current is leaking to earth |
| electrical-reasoning-applied-s04-q03 | C | Isolate at the supply, lock off the isolator, and prove the circuit dead with a tester that is itself proved before and after |
| electrical-reasoning-applied-s04-q04 | B | Voltage drop along the long, thin cable |
| electrical-reasoning-applied-s04-q05 | B | A reading close to zero ohms; a broken conductor reads as an open circuit |
