Defined as a device that changes sound into electric current?
The telephone does that!
What type of electric current changes direction?
AC current (alternating current) like in a wall outlet
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
What is an alternating circuit?
an electric current that changes it direction or strength repeatedly
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
What m-word is defined as a device that changes sounds into electric current?
microphone
How the charge on a wire changes when an electric current flows in the wire?
2 plus 2
What is AC current?
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
What is observed when electric current is passed through copper sulphate?
its colour changes 2 blue
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
Can a electric current affect a compass?
Yes. An electric current is surrounded by a magnetic field, and this will affect a compass. Please note that this is more noticeable in the case of DC - for AC, the current changes all the time, it changes very quickly, and the AVERAGE value of the magnetic field is zero.
Define alternating current definition?
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..
