![]() ![]() Which I'm going to carry on calling resistance because I'm not a sparky and I don't care. Which wouldn't actually be a circuit any more - but you know what I mean. An amp? I don't know the resistance of a person - but I doubt it's below 240 ohms. I suppose that's (slightly) better than having the full voltage across you, whereas if the device was off then you'd take the full whack because you're the only route that the current can take. If you had a high impedance and you were in parallel with the device then some of the current will still be going through the device (depending on your resistance vs the device's). If there were a fault in a device under load and you got involved in the circuit at the device itself then it'd depend on how you were arranged in the circuit. In practice I think you'd be thrown across the room before the fuse noticed, and you'd probably draw less than an amp anyway. I suppose you could argue that if there were lots of other loads the additional current you'd draw could blow the fuse (I'm assuming no RCD). if you've decided to bypass the protection on your plug socket and wire yourself into the mains then, no, I don't think the other loads would make a difference. You'd need to turn the microwave on to even use the kettle. Thinking about it, sockets in series would be weird. ![]() Your kettle doesn't get weaker because you turn the microwave on. purely theoretical and the real world doesn't gets a look-in) then you probably want to point out in your answer: ![]() If this is a physics homework question (i.e. So I don't know what sort of an answer you're after. best not find out eh? Oh yeah, make sure you have RCDs!īut this is your first post. If you're curious about how it works in practice then the answers above pretty much sum it up. I had a son would became a radio ham, and I had fitted two RCD's one for each fuse box old Wilex type now with MCB's in it back in 1991 at that time it was rare to have 30 mA protection never mind also on the lights, so had my son not passed his RAE at 16 I would not be here today.Ĭlick to expand.I think the answer partly depends on why you want to know. Had the cable not been RCD protected likely I would be dead. However it transpires some 30 years ago when the kitchen extension was built, the two way switches at the doors where not wired up to ceiling and then down to new switch, but horizontal around 4 corners to new switch, and I sawed through that cable, all house was RCD protected, so the RCD did trip, but with such good contact I ended up out for the count on the floor, still here 20 years latter to tell the tail, maybe if I had not been an electrician I would have tested for horizontal cables, but as an electrician I didn't expect anyone to run horizontal cables around a corner and around a pillar to the back door, without any conduit or trunking. I was very lucky, I had a new fridge/freezer so 22 years ago which needed a cold water feed, as it happened the loo was right above it, so micro bore pipe down the wall to a washing machine type tap, so lump of metal to space out two hack saw blades and slowly cut two parallel cuts the knock out plaster and fit pipe, quick test top and bottom no sign of cables. ![]()
