squirrely2005 Aug 26, 2011 Texas. From what I understand a pint is 16 ounces. I learned that from drinking Busch while living with my dad a few years ago. It just hit me the other day that I have a few glasses that are pint glasses but pouring a 12 ounce beer in them basically fills it up.
Hans Christian Oersted. In 1820, a Danish physics teacher observed that the current moving through a wire moved the needle on a nearby compass. when the current was reversed, the compass needle was deflected in the opposite direction. these magnetic effects ceased when the current in the wire stopped.
The speed at which a signal can propagate through a wire actually has little to do with the wire itself -- it is mostly determined by the permittivity and permeability of the dielectric material surrounding the wire, since it impedes the creation of the magnetic field that needs to surround the wire as current flows.
