Beer goes with peanuts, wine with cheese. Also, alcohol itself is high in caloriesâ7 calories per gram, almost as much as fat (9 calories per gram) and more than carbs or protein (about 4 per gram). Alcoholic beverages all contain calories, and most of the calories come from the alcohol.
Current and Power and Energy. The unit used to measure the flow of electricity, or current, is the ampere (A). The unit to measure power is the watt (W). Energy is measured in Joules (J). Amperes are really a measure of a rate of electron flow (electrons per second), or equivalently, how much charge is passed per second (Coulombs per second). 1 A = 1 Coulomb per second, and 1 electron has a charge of 1.602 * 10-19 Coulombs.
Energy Units and Conversions 1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power of a Joule of energy per second Power = Current x Voltage (P = I V) 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts.
