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.
What matters is the direction of current flow, since an LED is a type of diode, and for a diode to conduct, it must be forward biased. This means that the positive voltage must be connected to the anode, and the negative to the cathode (band end), the shorter lead.how more I am working with LED lights and I just wanted to know about the positive wire and the negative wire that come out from it (the positive one is the longer one I think).
