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.
Not only can you - you should! While vanilla flavoring is chemically identical to vanilla extract, the former tastes exactly as artificial as it is. Vanilla extract may cost up to ten times as much to buy, but at ~$10, it's still worth it. Try it - you'll notice a major difference in your baked goods right away. Here's a practical example: buy and taste test your supermarket's cheapest store brand vanilla ice cream ad compare it to a high end brand like Hagen Daz.
