AC current is considered better than DC current for electrical power distribution and transmission because it can be easily converted to different voltage levels using Transformers, allowing for efficient long-distance transmission. Additionally, AC current is able to travel over long distances with minimal power loss, making it more practical for widespread distribution of electricity.

Why is high voltage more efficient in electrical systems?

High voltage is more efficient in electrical systems because it allows for the transmission of electricity over long distances with less energy loss. When electricity is transmitted at high voltage, the current is lower, which reduces the amount of energy lost as heat in the transmission lines. This results in a more efficient and cost-effective distribution of electricity.


How does AC power work and what are its key components in an electrical system?

AC power, or alternating current power, works by constantly changing the direction of the flow of electricity. This allows for efficient transmission of electricity over long distances. The key components in an AC electrical system include a power source (such as a generator or power plant), transformers to change the voltage levels for transmission, transmission lines to carry the electricity, and distribution lines to deliver power to homes and businesses.


What is name for electrical current that changes direction at regular intervals?

The name for electrical current that changes direction at regular intervals is called "alternating current" (AC). This type of current is commonly used in homes and businesses as it allows for efficient transmission of electricity over long distances.


Why does an electrical cord need both a conductor and a insulator?

The conductor carries the electrical current while the insulator prevents the current from leaking out and causing electric shocks or fires. Both components are necessary for the safe and efficient transmission of electricity.


Can you define current density and explain its significance in the context of electrical engineering?

Current density is a measure of the amount of electric current flowing through a given area. In electrical engineering, it is important because it helps determine the distribution of current within a material or device, which is crucial for designing efficient and safe electrical systems. High current density can lead to overheating and damage, while low current density may result in inefficient operation. By understanding and controlling current density, engineers can optimize the performance and reliability of electrical components and systems.

What is the difference between heavy and light current in electrical engineering?

In electrical engineering, heavy current refers to high-power electrical systems typically used in power generation and distribution, while light current refers to low-power electrical systems used in communication and electronics. Heavy current systems operate at higher voltages and currents, requiring larger conductors and safety precautions. Light current systems operate at lower voltages and currents, focusing on signal transmission and processing with smaller components and lower power consumption.
