Hi Astrophysics,
I always wondered why they draw black holes like they do in that the accretion looks like it’s drawn in two planes. I would have thought it would have looked a bit more like a saturns rings? Or is it exactly like saturns rings but we see the whole ring bent round the top because a black hole bends the light around so we can see it? Or is it something else entirely that they are trying to depict here?
I live in Australia and I just did an audit of the power board that was sitting next to my bed. All four devices and the power board itself all have the insulated pins. I can’t remember the last time I saw one that didn’t have insulated pins. I’m sure they exist, but they are not common.
We also have RCD on all our circuits so if someone is able to short the pins, it will trip within 20ms or less.
