Bulacan State University CEEE 312 Basic Electrical Engineering Lecture No. 5 Principles of Alternating Current By: Engr. Ronan Cadmiel C. Castro BSEE MSEE Major in Power Systems (On Going-2 nd Term-Mapua University)
Objectives After studying this lesson, you should be able to: Understand how ac current and voltage are produced Use the instantaneous value formula in different situations Determine the phase relationship between two sinusoidal waveforms of the same frequency Understand the different characteristic of ac waveforms Solve simple ac resistive circuits
(120 V at 60 Hz) versus (220 V at 50 Hz)
GENERATING AN ALTERNATING VOLTAGE AC Voltage - one that continually changes in magnitude and periodically reverses in polarity .
VARIOUS SOURCES OF AC POWER
Other Waveforms
Which are alternating waveform?
ALTERNATOR In the simplified generator shown, the conductor loop rotates through the magnetic field and cuts lines of force to generate an induced ac voltage across its terminals.
ALTERNATING CURRENT GENERATION One complete revolution of the loop around the circle is a cycle .
ALTERNATING CURRENT GENERATION
EXAMPLE How many cycles are there on each situation?
