Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The вЂ¦ вЂў problem: which value of the changing voltage/current can be used to describe the effects? average вЂ“ not (= 0) maximum (or peak value or amplitude) вЂ“ not, just on ce/twice during the period root-mean-square = effective, r.m.s. value of alternating current or voltage r.m.s. values The same lamp is вЂ¦

Chapter AC вЂ“ Alternating Current Circuits Page 1 At first glance, this graph just shows a jumble of sine waves. They all have the same frequency, but their amplitudes and phases are different. One of our goals in this chapter is to make some sense of this jumble. The вЂ¦ Alternating-Current Circuits 12.1 AC Sources In Chapter 10 we learned that changing magnetic flux can induce an emf according to FaradayвЂ™s law of induction. In particular, if a coil rotates in the presence of a magnetic field, the induced emf varies sinusoidally with time and leads to an alternating current (AC), and provides a source of AC power. The symbol for an AC voltage source is An

(2) Alternating current or voltage source (AC source) in which the current or voltage constantly changes with time. The voltage of the electrical power source that we use in our homes or offices (line voltage) is a sinusoidal signal that goes through a complete cycle 60 times in one second. In this section we will discuss how single phase AC What is Alternating Current??
