Question

the most common source of alternating voltage is​

Answer 1

Answer:

The most common type of AC is the sine wave. The AC in most homes and offices have an oscillating voltage that produces a sine wave. Square waves are often used in digital and switching electronics to test their operation.

Answer 2

Answer:

The most common source of alternating voltage is an AC generator.

Explanation:

• An AC generator is basically a machine that converts mechanical energy into electrical energy.
• An AC Generator's input supply is usually mechanical energy supplied by steam turbines, gas turbines and combustion engines etc.
• The output is an alternating electrical power in the form of alternating voltage and current.
• The alternating component can be described in terms of sine or cosine functions and the reason for this is most of the motion observed in nature is of oscillating type.
• AC generators work on the principle of Faraday's law of electromagnetic induction.
