FAQs on AC Basics: Learn All About Alternating Current Video Lecture - Network Theory (Electric Circuits) - Electrical Engineering (EE)

1. What is alternating current (AC)?
Ans. Alternating current (AC) is an electric current that periodically reverses direction. It is commonly used in homes and businesses to power electrical appliances and devices.
2. How does alternating current differ from direct current?
Ans. Alternating current changes direction periodically, while direct current flows only in one direction. AC is typically used for long-distance power transmission, while DC is used for shorter distances and in electronic devices.
3. What are the advantages of using alternating current?
Ans. Alternating current is more efficient for long-distance power transmission, as it can easily be converted to different voltages using transformers. AC is also safer for use in homes and businesses compared to direct current.
4. How is alternating current generated?
Ans. Alternating current is generated using a device called an alternator, which converts mechanical energy into electrical energy. Alternators are commonly used in power plants to produce electricity for the grid.
5. Can alternating current be converted to direct current?
Ans. Yes, alternating current can be converted to direct current using a device called a rectifier. Rectifiers are commonly used in electronics and power supplies to convert AC power to DC power for use in various devices.
