How electric current generate?
electric current generate so many types one of mechanical energy convert electrical energy by using generator
Can an electric current generate an electromagnetic wave?
Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
What is a Tesla coil used for?
to generate electricity to demonstrate the ac current is harmless
When a wire carries an electric current it products a?
It produces a magnetic field. Vice versa, when you run a magnet past a wire you generate an electric current. Electricity and magnetism are related. If you have electricity you can generate magnetism, if you have a magnet you can produce electricity.
How are street lights switched ON automatically on a cloudy afternoon?
streetlights have whats called a photovoltaic cell on top of there casings,this cell works by using sunlight to generate a little current,when there is less sun it will generate less electricty,when it generates less than a certin current it will triger a switch in the streetlight,when the sun comes back out bit by bit it will generate current again until a certin point which is related to how bright the sun is shining and then the light will turn back off

What is the name of device which generate current?
A generator or an alternator.
What is a example of alternating current?
in the generating stations we generate only alternating current...this is the best example
Why potentiometer is called passive transducer?
because potentiometer generate a own current
What is a Tesla coil used for?
to generate electricity to demonstrate the ac current is harmless
Why solar panels generate dc current?
Because it creates solar power
What must a magnet do to generate an alternating current?
To generate an alternating current, a magnet must use kinetic energy. This means that the magnet must move at a certain speed and velocity in order to create a strong enough energy charge.
When a wire carries an electric current it products a?
It produces a magnetic field. Vice versa, when you run a magnet past a wire you generate an electric current. Electricity and magnetism are related. If you have electricity you can generate magnetism, if you have a magnet you can produce electricity.
When a battery is discharged and can no longer generate a current what can be concluded?
The battery is as flat as a pig's nose !
What do you mean by Electro Luminescence?
A device that glows when excited by electric current, but does not generate heat.
What resistance would produce a current of 25 ampers?
resistance does not produce currents . you need source (like voltage source , current source ,or , discharging capacitor) to generate current .
