MM Posted July 9, 2010 Author Report Share Posted July 9, 2010 I'm at work tonight I'll weigh my Xd card on one of the electronic balances in one the labs. I think they are accurate to 1000th of a gram ? and as sad as i might sound, id be very interested in the results. Quote Link to comment Share on other sites More sharing options...
DSPUK Posted July 9, 2010 Report Share Posted July 9, 2010 After reading this topic "we will all be interested in result." - been the highlight of my day this. Dave Quote Link to comment Share on other sites More sharing options...

shot shot Posted July 9, 2010 Report Share Posted July 9, 2010 does electricity have weight? in lamens terms, yes, it does Quote Link to comment Share on other sites More sharing options...

shot shot Posted July 9, 2010 Report Share Posted July 9, 2010 lay it on me ok, here goes (A level physics at work) an electron weighs 1.6x10*-19 kg. Electricity in it's purest form, when it's jumping between two points will have a mass. The principal cannot be applied in metal though, because as current flows, the electrons in one place are being replaced as they move. So the metal in the wire stays at the same mass. Oh, and if I'm to be really anal, they don't have a "weight" per say, they have a "mass", as the weight of something is only the product of the force of gravity acting upon a mass (needs to get out more) shot shot Quote Link to comment Share on other sites More sharing options...
flash Posted July 9, 2010 Report Share Posted July 9, 2010 (edited) to be really anal about the weighing of the sd card, then it needs to be done inside a hermetically sealed chamber cleared of every particle of dust etc. otherwise god knows what other microscopic items may be on it, which will then alter the results.

Ozzy Fudd Posted July 10, 2010 Report Share Posted July 10, 2010 right, so if electricity has a mass, does a chrged battery weigh more than a flat one? Quote Link to comment Share on other sites More sharing options...
shot shot Posted July 10, 2010 Report Share Posted July 10, 2010 right, so if electricity has a mass, does a chrged battery weigh more than a flat one? batteries don't give out electricity, they just push it one way and pull it the other (sort of) Quote Link to comment Share on other sites More sharing options...
Diceman Posted July 10, 2010 Report Share Posted July 10, 2010 I heard a debate on the radio on this topic, they actually concluded that a full memory card actually weighed less than an empty one - can't remember the details but something to do with the state of charge of the electrons. Not a difference you could actually weigh though, at least not with any commercially available scales! Quote Link to comment Share on other sites More sharing options...
