Alternating current (AC) is a type of electrical current that periodically changes direction. Unlike direct current (DC), which flows in only one direction, AC alternates between positive and negative cycles. AC is used in various applications because of its ability to be easily transmitted over long distances and its versatility in powering different devices. Some common uses of AC include:
1. Powering homes and buildings: AC is the primary form of electrical power used in residential and commercial buildings. It is distributed through power grids and delivered to our homes, providing electricity for lighting, appliances, heating, and cooling systems.
2. Industrial applications: AC is widely used in industries for powering machinery, motors, and equipment. It is efficient for running heavy-duty equipment and allows for precise control of speed and torque in motors.
3. Electric transportation: AC is used in electric vehicles (EVs) and hybrid vehicles. It provides the power needed to charge the batteries and run the motor, allowing for eco-friendly and efficient transportation.
4. Powering electronic devices: Many electronic devices, such as laptops, smartphones, and televisions, use AC power. However, these devices typically convert AC to DC internally to power their components.
5. Renewable energy generation: AC is the standard form of electricity generated by most renewable energy sources, such as wind turbines and solar panels. It can be easily converted to the appropriate voltage levels for distribution and use.
6. Medical equipment: AC power is crucial in hospitals and medical facilities for running life-saving equipment like MRI machines, X-ray machines, and surgical tools.
7. Lighting: AC power is used to illuminate our homes, offices, streets, and public spaces. It is the primary source of power for lighting fixtures, including incandescent bulbs, fluorescent lights, and LED lights.
These are just a few examples of the many uses of alternating current. Its ability to be easily generated, transmitted, and converted to different voltages makes it an essential part of our daily lives.
Verified answer
Answer:
Alternating current (AC) is a type of electrical current where the flow of electrons switches back and forth at regular intervals. As a result, the voltage level also reverses with the current.
AC is the most commonly used and most-preferred electric power for household equipment, office, buildings, etc.. It is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket
