Is it dangerous to touch the conductors of a power cable?
This concerns electricity available in households, specifically AC at 230 V.
| Conductor | Same potential as ground? | Dangerous? |
|---|---|---|
| Phase | No | Yes 1 |
| Neutral | Yes | No |
| Protective | Yes | No 2 |
1 It actually depends on the isolation towards the ground.
2 That conductor transmits current just in an error case.
How do I find out if an electronic component is broken?
| Component | Broken |
|---|---|
| Diode (silicon) | Multimeter: Not 0.7V/0.0V in/against flow direction |
| Capacitor | Optical: The head is convex |
