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.
No. Where vanilla frosting may taste like vanilla, it is not actually vanilla. Vanilla extract is from vanilla bean, and has no sugar or artificial ingredients added to it. Itâ¦ is a liquid, and the taste of whatever you were baking would be seriously compromised if you didn't use the real stuff.
