Alternating Current

Alternating Current is a type of electrical current that reverses direction periodically. It is the form of current used in the vast majority of electrical power distribution systems, and is also used in many electronic devices. Alternating current is generated by an alternator, which is a type of electrical generator that converts mechanical energy into electrical energy.

What is Alternating Current?

Alternating current is a type of electrical current that flows in one direction for a period of time, and then reverses direction and flows in the opposite direction for the same period of time. This cycle is repeated continuously. The waveform of alternating current is a sine wave, which is a smooth, continuous curve that repeats itself over time.

The frequency of alternating current is the number of times the current changes direction in one second. The frequency of alternating current is measured in hertz (Hz). The standard frequency of alternating current in the United States is 60 Hz, which means that the current changes direction 60 times per second.

How is Alternating Current Used?

Alternating current is used in a wide variety of applications, including:

• Power transmission: Alternating current is used to transmit power over long distances. This is because alternating current can be stepped up to very high voltages, which reduces the amount of power loss over long distances.
• Electrical motors: Alternating current is used to power electric motors. Electric motors are used in a wide variety of applications, including industrial machinery, appliances, and vehicles.
• Electronics: Alternating current is used to power electronic devices. Electronic devices include computers, televisions, and cell phones.
