Alternating currents is an important Physics topic and questions from this chapter are frequently asked in engineering entrance exams such as JEE Main, BITSAT, VITEEE, and SRMJEEE.
If you are preparing to appear for any of these exams then make sure that you are thorough with all of the important topics. Direct current (dc) refers to systems in which the source voltage is constant.
Alternating current (ac) refers to systems in which the source voltage varies periodically, particularly sinusoidally. The voltage source of an ac system puts out a voltage that is calculated from the time, the peak voltage, and the angular frequency.

Author: Daniel Harvey Braymer; Practical alternating currents and alternating current testing book N.A. Both Alternating Current and Direct Current describes the two types of current flow in a circuit. In direct current, the electric charge or current flows in one direction.
In alternating current, the electric charge changes direction periodically. The voltage in AC circuits also sometimes reverses because the current changes direction.

ALTERNATING CURRENTS OF ELECTRICITY AND THE THEORY OF TRANSFORMERS MAGNETIC PRINCIPLES 1. Measurement of Magnetic Field.—Since the magnetic field due to an electric current is of far more practical importance in the case of an alter nating current than in that of a continuous current— which, so long as it does not change in strength.
Alternating currents produce different responses in resistors, capacitors, and inductors than direct currents do. Alternating currents and voltages Figure 1 shows the plot of alternating voltage and alternating current as a function of time in a circuit that has only a resistor and a source of alternating current — an ac generator.
Some day we shall have occasion to describe the two alternating current motors devised by Mr. Tesla as long ago as At present, we shall content ourselves with recurring to his magnificent experiments on high potentials and alternating currents of great frequency, of which we have already given a complete idea in summarizing the.
Page 8 - The volt is the practical unit of electromotive force, and is the electromotive force which will maintain a current of one ampere through a resistance of one ohm. It is equal to 10s CG Appears in 7 books from There are two types of current, direct current (DC) and alternating current (AC).
DC is current that flows in one direction with a constant voltage polarity while AC is current that changes direction periodically along with its voltage polarity. Thomas Edison and Alessandro Volta were pioneers in DC current and wrote much of electricity’s. Alternating Current Review Questions 30 Terms.

Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps.

Alternating current (AC), flow of electric charge that periodically reverses. It starts from zero, grows to a maximum, decreases to zero, reverses, reaches a maximum in the opposite direction, returns again to the original value, and repeats this cycle.

For Electromagnetic Induction and Alternating Currents, chapter concepts in NCERT are enough but you will have to practice lots of questions including previous year questions and you can follow other standard books available for competitive exam preparation like Concepts of Physics (H.
Verma) and Understanding Physics by D. Pandey. Alternating Current (AC) Alternating current is defined as the flow of charge that changes direction periodically. The result obtained will be, the voltage level also reverses along with the current. Basically, AC is used to deliver power to industries, houses, office buildings, etc.
Theory 3: Alternating Currents, Motors, Generators, and Transformers With this interactive and easy-to-use online course you’ll learn where alternating current comes from and why it’s used. You’ll gain a solid understanding of motors, apparent power, true power, unity power, power factor, and transformers.
Alternating current is represented by a periodic function. The waveform of the current may sinusoidal, square, triangular or sawtooth type etc.
The average value of an pure alternating current is zero. These are the waveforms of different alternating currents. The ALTERNATING CURRENTS system has offered so many advantages that at present electrical energy is universally generated, transmitted and used in the form of alternating current.
Even when d.c. energy is necessary, it is common practice to convert A.C. into D.C. by means of rotary converters or rectifiers. ALTERNATING CURRENT FUNDAMENTALS, 8E, an industrial standard for over thirty years, has been updated to provide readers with the most current information available on the essentials of alternating current.

Although DC, the unidirectional flow of an electric charge, is perhaps one of the simplest of electrical engineering concepts, it is not the only “type” of electricity in use. Both AC and DC describe types of current that flow in a circuit.
