If you sing a high pitched note how does the electric current in the microphone change?

The acoustic sound pressure wave of the high pitched note is converted by a microphone to an equal audio voltage of that pitch, which will be amplified and usually recorded. Forget the electric current and the electric power. Try to learn about the microphone output in mV/Pa and understand the microphone: Pascals in and millivolts out. That's it. Scroll down to related links and look at "Microphone Sensitivity".

How do you change the volume of the recorder?
im pretty sure that you can hold a microphone up to the bottom of the recorder but it might not work:P
What is an acoustic electric guitar?
Acoustic-electric guitars are acoustic styled guitars with a pickup either outside or inside the hollow body. You plug a cable into it like you would a normal electric guitar and it can be used through an amplifier to make the sound louder. They can also be played without being plugged in just like a normal acoustic guitar
What instruments are un-pitched?
i dont know what un-pitched instruments are
How do you change the pitch of piano?
We can change its pitch by finding the middle C so that we can be able to know which is high-pitched or low-pitched. If you want high pitch you play keys which are on the right. If you want low pitch you can play the keys which are on the left.
When did Northern Electric change its name?
In 1976 it changed its name to Northern Telecom
How can electric current change?
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.
How can the flow of electric current be started and stopped?
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.
How does microphones change sound energy to electrical energy?
Teh varying pressure of the air (the sound) causes a varying electric potential in microphones. There are various techniques, one is called "dynamic microphone" whereby a membrane with a coil is allowed to move inside a magnetic field. The sound moves the membrane, the movement of the coil inside the magnetic field generates a current in the wire which is the signal. Ten kinds of microphone are discussed on Wikipedia (see Related link below)
Do magnetic effect of electric current causes a change in colour in a solution through which electric current is passed?
i don't believe it does
Can argon change color?
When excited by electric current flowing in it.
Electric current in which electrons repeatedly change direction?
AC
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
Does increased current flow change the sound of an electric buzzer?
yes
What is constant electric current?
That means it doesn't change over time.
What metal doesn't change when electricity goes through it?
Electric current is a flow of electric charge through a medium
Does current effect the resistance in an electric series circuit?
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
