The potential difference between two points in an electric circuit is the work done when a coulomb of charge passes between the points. You can calculate the size of a potential difference using this equation: V = W Ã· Q. 1  V is the potential difference in volts, V. 2  W is the work done (energy transferred) in joules, J.
Thanks for you help. Yikes, now you got me thinking! I went and my bottle of wilton vanilla and sure enough, it was like I went to the medicine cabinet and opened the bottle of rubbing alcohol! Extract is about 35% or so alcohol, so it may smell like alcohol - but the primary aroma should be vanilla.
Wilton clear vanilla should smell like vanilla. It sounds like yours has gone bad. I've had several bottles of clear vanilla (Wilton and CK brand) go bad, and they smell like pure alcohol when they do. Yeah, I usually buy the big bottles from Michaels or Hobby Lobby, but late one night I ran out and had to get it from Walmart, and in a little bottle.
