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.
Pure Vanilla Extract is a flavouring derived from an orchid in the genus Vanilla native to Mexico, the only edible fruit of the orchid family, which is the largest family of flowering plants in the world. Vanilla Extract is produced by drying and curing the green bean pods from the Vanilla plants.
