A thermal electric cooler uses the?
Peltier Effect
What is inductive current?
Induction: Uses electrical energy to create a magnetic field and the magnetic field restores energy back to the line when it collapses.Electrical Theory, Tom Hernry, pp26
What uses a magnetic field to turn motion to electricity?
A microphone is a good example of a device that utilizes electromagnetic induction (Faraday's Law) to convert motion (vibrations in air) into electricity. The sound vibrates a membrane attached to a little magnet inside a coil of wire. The changing magnetic field induces a current in the wire.
What are the properties of Electromagnetism?
An electromagnet is created when an Fe core is wrapped in a conductor and an electric current goes through the conductor; magnetism and electrical current have a symbiotic relationship -- when a conductor is moved in a magnetic field, electrons start to move and when electrons move through a conductor, a magnetic field is created around the conductor; a simple motor uses an electromagnet to do work.
What instrument is used to magnify small object?
An electric guitar and some old organs and keyboards use magnets wrapped with fine wire to detect movement in the field. In an electric guitar that would be the guitar string moving near a pickup. It makes electricity which is amplified.
What is galvanometer magnetic force and motor effect?
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy. In a galvanometer, the concept of the motor effect is used for it to detect and measure the magnitude of small electric currents as an instrument. A galvanometer uses radial magnets which cover more area of the rotor (this is where the needle is attached), as this rotor consists of an armature and loops of wire, it is perpendicular to the magnetic flux lines of the radial magnet. Therefore as the current flows through the coil, a magnetic field is produced, and the motor effect occurs allowing the needle to move on the scale.
Name two deviceswhich use currentcarrying conductor and magnetic field?
Electric motor and loud speakers are the two devices that uses current carrying conductor and magnetic field.
Does an electromagnet use an electric force or a magnetic force?
it uses electric force
What kind of electric current does an electric stove use?
An electric stove uses Alternating Current to operate.
What device uses motion in an electric field to produce an electric current?
electric genarator
A thermal electric cooler uses the?
Peltier Effect
Does the ear drum have an electric current?
Actually your eardrum does not have electric current and in which it only uses sound so if you get an electric shock it does not harm your ear drums.
What sentence uses the the words electric circuit in it?
The electric circuit has a current running through it.
What is a device that uses electric current to represent coded information?
An electronic device uses electric to represent coded information. Variations in the current are converted to codes used by the electronic device.
What is sensor carburetor and electronic carburetor?
The sensor carburetor uses the sensors in its operation while the electric carburetor uses the electric current in its operation.
What are the uses of solenoid?
Solenoids are coils of wire that create a magnetic field when an electric current passes through it. These are used in the alternator of a car to create electricity. Solenoids are also used in generators to create electricity in power stations and in transformers to change the voltage of an AC current.
Is watching a television current or static electricity?
The operation of the television, as all electronics, involves electric currents. If your TV uses a CRT display as it operates it happens to build a large static electric field on its face, as a side effect of that operation.
