2005年2月2日 · My guess is that the current shorts out the toaster and trips the circuit breaker, but I can't see why the person in the tub would get a shock. I'd figure the hot and the neutral in the toaster, once exposed to the water, would close the circuit and trip the breaker. The person in the tub would not be part of the circuit. Thanks for any insight.

2004年11月14日 · I had a question about electricty and being electrocuted. It is well known that if you drop a toaster that is plugged in into a bathtub you are sitting in, you will be electrocuted. My question is, how far reaching is the electrical energy in a body of water? For example, if I am in...

2006年6月18日 · Many commercial wet benches routinely use DI by the hundreds of galleons, so a bathtub full is not all that remarkable, as long as the bathtub is made of PTFE or some similar plastic. The reason a bathtub full of soapy water or even tap water is an excellent conductor is because it is NOT pure, in fact it is a LONG way from being pure.

2011年11月7日 · The metal drain pipe for the bathtub acts like a ground path, so there is a "ground fault" created when the dryer falls into the slightly conductive bathwater. If your body is in the water between the dryer and the drain, you may have enough current pass through your body to stop your heart.

2023年2月3日 · Hey there, I honestly don’t know if this is the right place for this, but I figured I would ask. lets say you are going to take a bath, but someone just took a shower and you know your hot water heater will be running low on the goods. Just for arguments sake, let’s say you have just enough...

2007年1月1日 · Toasting in a toaster is usually considered cooking by (infra red) radiation. But the hot coils touch the toast so an element of heating by conduction occurs as well. Are they both equally as valid or is one more valid than the other. If the latter than which one and by …

2009年9月5日 · Ok say there is a force T acting on the toaster at θ above the horizontal. The y component is TSinθ and the x component is TCosθ. We want TCosθ>fstatic so it will move. TCosθ>N(mu) TCosθ>12.74(.350), TCosθ>4.459. Now Cosθ ranges from 1 to 0. The higher Cosθ is, the lower T will be. The highest Cosθ goes is 1 so T>4.459. What am I ...

2009年1月8日 · It appears everyday electric space heaters, that is resistance heaters, are virtually 100% efficient. No matter what resistance material is used, there is only 3.413 BTU per watt hour of heat output; in other words, all 1500 watt heaters consume the …

2017年6月23日 · Is there a generally accepted ball-park figure for the force a human can apply to a lever? Obviously, I am not thinking of an Olympic weight-lifter or of my three-year-old granddaughter - just the turning moment generated by the 'average' person standing up and pulling/pushing on an horizontal...
