What do you measure with electric current?
I presume you mean what do you measure electric current with. You would use an ammeter.
What do you nedd to produce a continuous path of electric current?
to produce a continuous psource of electirc current, you would need electrons.
How would you sketch the magnetic field lines of a coil with electric current?
like a butterfly!
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
What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
What is the need of lamination in transformer?
The laminated plates prevent eddy currents from forming and thus creating unwanted magnetic flux which would counter the flux needed to induce the electric current in the secondary coil
What do you measure with electric current?
I presume you mean what do you measure electric current with. You would use an ammeter.
Is arc welding an example of electric current?
No, an example of an electric current would be using a battery to light a lightbulb.
Would increasing the resistance increase electric current?
no
What would you expect to conduct an electric current?
the metal
As electric generatar produce electric current due to magnetic induction than why current don't produce in electric motor as magnetic induction should also occur in electric motor?
I will attempt to answer the question I think your asking: 'If an electric generator produces an electric current due to magnetic induction, then why isn't a current produced via the same mechanism in an electric motor?' The answer to the best of my understanding is that it is, or at least, it would be. The reason is that in a generator a conducting wire is rotated in a magnetic field and this induces a current as each charged particle experiences a force as determined by F=q(vxB) [this is the vector form of the equation using the vector product] or F=Bqv if you are unfamiliar with vectors. As this causes electrons to move this manifests itself as an alternating current in a wire. Conversely in a motor and alternating current is passed through a magnetic field in a coil of wire, this time the wire now experiences a force F determined by F=I(lxB). This produces a torque on the centre of the motor and it is this torque that drives the motor. However if you were to rotate the coil of the motor externally without supplying a current to it then the reverse process would take place. This would induce an AC current in the motor which would now function as a generator. As a aside if this current was then driven through the generator it would then rotate exactly as the motor did.
What charge is an electric current?
Electric current is both positive and negative. If there were only one of those it would be an open circuit and it would not work. The particles would be able to flow one way but not the other.
Which instrument would measure an electric current?
A voltmeter or a multi-meter.
Electric current is sometimes incorrectly defined as simply a flow of electrons What is wrong with this definition?
Electric current is the rate of flow of electrons.AnswerA more accurate definition of electric current would be that it is a flow of electric charges. While current flow in a metallic conductor is, indeed, a flow of electrons, in other conductors -such as electrolytes- current flow may be a movement of ions. So, it would be more accurate to define current in terms of charge flow, rather than in terms of electron flow.
Will lightning start your car?
It would have to induce the right dc current in the starter motor and energise the ignition at the same time, so unlikely
How much current should be given to mice in Electric Shock experiment?
The amount of current that should be given to mice in Electric Shock experiments would depend on what is being tested
What would happen if there is no an electric switch in a curcuit?
Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.
