Answer:

Power is calculated by multiplying voltage by current.

Explanation:

If you're calculating the power of an athlete who is lifting weights,

or the power of a windmill that is pumping water from a well, or

the power of two horses turning millstones, then those electrical

units won't help at all.

But if you happen to be calculating the power delivered to an

electrical circuit or dissipated by an electrical device, then you

can use ...

(voltage) times (current)

(voltage)² divided by (resistance)

(current)² times (resistance) .

The choice just depends on which quantities you know

or can easily measure.

<h3>What is noise?</h3>

Unwanted sound that is regarded loud, unpleasant, or disruptive to hearing is called noise.
Physically speaking, there is no difference between unwanted sound and desired sound because both are vibrations traveling through a medium like air or water.
When the brain receives and interprets a sound, a difference occurs.
Decibels are used to measure sound (dB).
A motorcycle engine operating is roughly 95 dB louder than regular conversation, which is around 60 dB louder than a whisper.
Your hearing may begin to be harmed if exposed to noise over 70 dB for an extended period of time.
Your ears can suffer instant damage from loud noise above 120 dB.

<h3>What is sound intensity?</h3>

The power carried by sound waves per unit area in a direction perpendicular to that region is known as sound intensity or acoustic intensity.
The watt per square meter is the SI measure of intensity, which also covers sound intensity.
