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".
im pretty sure that you can hold a microphone up to the bottom of the recorder but it might not work:P
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
i dont know what un-pitched instruments are
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.
In 1976 it changed its name to Northern Telecom
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.

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)
i don't believe it does
When excited by electric current flowing in it.
AC
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
Increase or decrease in potential results in the change in direction of the flow of electric current.
yes
That means it doesn't change over time.
Electric current is a flow of electric charge through a medium
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
