The electrostatic unit (esu) of a quantity of electricity refers to a point charge that when placed at a 1-centimeter distance in air from a similar and equal charge repels it with a force of 1 dyne. To convert a number of such units to coulombs, which are the practical units, divide the total number of esu by 3 ϫ 109. The number 109 (pronounced “ten to the ninth power”) is the same as 1,000,000,000, but is much easier to express. This is a system of notation used to express large quantities in a condensed form.
18 Chapter 2 Permeability (): Expresses the ratio of magnetic flux density produced in a magnetic substance to the magnetic field intensity that occasions it. Temperature Units Celsius (ЊC): A temperature scale, formerly termed centigrade and used extensively in electrical work and in the metric system. Fahrenheit (ЊF): A temperature scale commonly used under our system of temperature recording. On the Celsius scale, 0°C is the temperature at which water freezes, and 100°C is the temperature at which water boils.
37 inches. Hence a centimeter is 1/10–2 meter. The prefix mega means 1,000,000 times the unit referred to. Thus 1 megohm is equal to one million ohms, or 106 ohms. The prefix kilo means 1000 times the unit referred to. Thus a kilowatt equals 1000 watts, or 103 watts. The prefix hecto (which we won’t refer to much) means 100 times the unit to which it refers. Thus a hectowatt is equal to 100 watts, or 102 watts. Definitions A number of definitions will be given at this point in the course. There will be others given as we progress.
