Automated Dorm Room Causes a School Inquiry

First time accepted submitter ElectronicHouseGrant writes "Freshman Derek Low rigged up his Berkeley dorm room with something he calls B.R.A.D., which is short for 'Berkeley Ridiculously Automated Dorm.' The room includes automated lighting, drapes, music, motion detection, and more. He can control everything through voice recognition, but a wireless remote, his iPhone and his iPad are also in on the control party. Derek started the install on February 4 and finished just a few days ago."

      Actually that's not the most dangerous scenario. The most dangerous electrical shocks are straight through the blood-stream - blood has a much lower resistance than skin - and goes straight over the heart. My father is an electrical engineer - his final thesis included a proof that just 1v straight to the blood is deadly.

      Here's what really happens in most electrical shock deaths: the current causes a muscle spasm preventing you from letting go. Now you have voltage over high resistance - so the current isn't fatal. However - voltage against high resistance is known to produce large amounts of heat (that's how stove plates work). The heat starts to burn you, eventually it burns through the skin - and when that happens the voltage goes straight through the bloodstream - which is an excellent conductor - bang, you're dead.

      This is why we teach people that if somebody is experiencing electrical shock you should use a non-conductive object (such as a wooden broom) to push him away rather than try to do so with your hands - the risk is too high of spasming into place yourself.
      110v for a few seconds won't harm you, but if you are unable to break the circuit, 110v for 5 minutes almost certainly WILL.

      oltage against high resistance is known to produce large amounts of heat (that's how stove plates work)

      No, not quite. Power dissipated (in this case the "heat") is V^2/R. Higher resistance means less power. Stove elements work by putting mains voltage across a fairly low resistance, causing plenty of current, power, and heat. In actuality, 110 Vrms is not enough to produce much in the way of a burn.

      Now, you are correct about the bloodstream being a good conductor. It is quite rare that a live wire will directly contact the bloodstream, though -- but it does not need to. The resistance of human skin is non-linear, and is actually lower at higher voltages. Additionally, there is plenty of capacitance involved in the body's circuit*, meaning that the full impedance at 60 Hz is lower than just the DC resistance. If there is a route through the heart, and the "let-go threshold" has been exceeded, then even 110 V can be deadly -- no burns necessary.

      *The human body model capacitance is only 150 pF, but this represents the body's capacitance to the outside world. The actual capacitance through a narrow layer of skin is many orders of magnitude higher, though I can't get a good source for the actual value.
