Chapter 7: Alternating Current 7.1 Introduction We have so far considered direct current (dc) sources and circuits with dc sources. These currents do not change direction with time. But voltages and currents that vary with time are very common. The electric mains supply in our homes and offices is a voltage that varies like a sine function with time. Such a voltage is called alternating voltage (ac voltage) and the current driven by it in a circuit is called the alternating current (ac current). Today, most of the electrical devices we use require ac voltage. This is mainly because most of the electrical energy sold by power companies is transmitted and distributed as alternating current. The main reason for preferring the use of ac voltage over dc voltage is that ac voltages can be easily and efficiently converted from one voltage to the other by means of transformers. Further, electrical energy can also be transmitted economically over long distances. AC circuits exhibit characteristics that are exploited in many devices of daily use. For example, whenever we tune our radio to a favorite station, we are taking advantage of a special property of ac circuits – one of many that you will study in this chapter. Representation Of Ac Current And Voltage By Rotating Vectors— Phasors In the previous section, we learned that the current through a resistor is in phase with the ac voltage. But this is not so in the case of an inductor, a capacitor, or a combination of these circuit ...

1. Audio signals are alternating current and so are attenuated by such capacitances. 2. Brown then applied 330 volts of alternating current which killed the dog. 3. All of these impulses flow in alternating currents through the era's art. 4. Lown devised a defibrillator that utilized direct current instead of alternating current. 5. Since the exponential is complex, the solution represents a sinusoidal alternating current. 6. Familiar examples of oscillation include a swinging pendulum and alternating current power. 7. An alternating current of one volt is then passed through the body. 8. The electric chair used alternating current at similar voltages, with high amperage. 9. The Hamburg service had established an experimental alternating current line in 1907. 10. The use of alternating current was still under development during this time. More sentences:1

These answers will similarly help students in scoring better marks with the assist of properly illustrated Notes as a way to similarly assist the students and answering the questions right. NCERT Notes For Class 12 Physics CHAPTER 7 ALTERNATING CURRENT Class 12 Physics CHAPTER 7 ALTERNATING CURRENT AC Voltage and AC Current • A voltage that varies like a sine function with time is called alternating voltage (ac voltage). • The electric current whose magnitude changes with time and direction reverses periodically is called the alternating current (ac current). Advantages of AC: • Easily stepped up or stepped down using transformer • Can be regulated using choke coil without loss of energy • Easily converted in to dc using rectifier (Pn – diode) • Can be transmitted over distant places • Production of ac is more economical Disadvan...
