REVIEW OF ELECTROMAGNETISM Direct Current Fundamentals discussed the following two basic principles of electromagnetism: (1) a magnetic field surrounds every current-carrying conductor or coil winding, and (2) an increase or decrease in the current causes an increase or decrease in the number of lines of force of this magnetic field. 43 44 ALTERNATING CURRENT FUNDAMENTALS A changing magnetic field induces a voltage in the conductor, coil, or circuit. This voltage is proportional to the rate of change of the lines of force cutting across the conductor, coil, or circuit.
For example, ac voltmeters and ac ammeters indicate effective values. 707 of the instantaneous maximum values. There are some applications in which the average values of current and voltage are necessary. Some of these include rectifier units that use solid state devices such as diodes and silicon controlled rectifiers (SCRs) to convert alternating current into direct current. Determining the Average Value It was pointed out earlier that if an attempt is made to determine the average value of either a sine wave of voltage or current, the obvious procedure is to determine the average value of one alternation of a sine wave.
24 I 2 Rt The calorie unit of the metric system is widely used. However, it is important that the student be familiar with another unit called the British thermal unit. The British thermal unit (Btu) is the amount of heat required to raise one pound of water one degree Fahrenheit. Because 1050 J is also required to raise one pound of water one degree Fahrenheit, 1050 J ϭ 1 Btu. 000952 I2Rt where H I R t ϭ heat energy, in British thermal units ϭ current, in amperes ϭ resistance, in ohms ϭ time, in seconds If the product in joules or watt-seconds in this formula is divided by 1050, the result is the heat energy in Btu.
