Study Notes
Alternating Current (AC) in Electric Power Circuits
- The usual waveform of alternating current in most electric power circuits is a sine wave.
- Alternating current is used for electrical energy distribution due to its ease of transformation to high or low voltages using transformers.
Delivery of Electric Power
- Electric power is delivered to businesses and residences as alternating current.
Information Carried by Alternating Current
- Alternating current is used to transmit audio signals, such as music and voice, in applications like radio broadcasting and telephones.
Specialized Applications of Alternating Current
- In certain applications, like guitar amplifiers, triangular or square waveforms are used instead of sine waves.
