How EDM wire cut machine works?

in wire cut, a wire is passed through a metal or is placed next to it. the wire works as one of the electrodes while the work piece would be the other one; using andielectric liquid to isolate the wire from the work piece. the electricity is conducted in the wire. as the wire gets closer to the work piece the electricity (electrons) tend to jump from the wire to the work piece in order to create a complete electrical circuit that's when a spark is formed. the dielectric helps us by isolating the wire from the work piece as long as it can, so we can have enough difference in potential between two electrodes before the spark is formed, it works like capacitor stopping the current from going through it until it collapses at a potential and enough current passes through at once. A collateral effect of this passage of current is that material is removed from both the electrodes.


What can be done to minimize eddy current losses?

Changing magnetic field causes to produce eddy currents that are confind within the core of transformer. these are like circulating whirls inside the core. these can be eliminated by making the core of thin layers. "Eddy current losses occur whenever the core material is electrically conductive. Most ferromagnetic materials contain iron: a metal that has fairly low resistivity (roughly 10-7 Ω m). The problem is intuitively obvious if you consider that the magnetic field is contained within a 'circuit' or loop formed by the periphery of the core in the same way as it is contained within a turn on the windings. Around that periphery a current will be induced in the same way as it is in an ordinary turn which is shorted at its ends"


What happens when emitter and collector of a transistor are short?

The transistor acts like a normal pn diode. in NPN transistor the both n i.e.,collector and emitter ane shorted then they become a n and other is p so pn diode is formed. When the emitter and the collector of a transistor are short, the emitter current =the collector current.

Are amps constant in a parallel circuit?

The short answer is NO. PARALLEL circuits are those in which two or more physical branches (the wirings) are connected together at the endpoints of each branch. This means that each branch has the same voltage V applied to it (across it). Since each branch may have different types of components (the loads), the current in each branch can be different, since current I is the voltage V across a branch divided by the effective load resistance R, then I= V/R . Since the voltage across each branch is the same, if R varies in each branch then current I must vary in each branch. A SERIAL circuit has the SAME current since it is formed by connecting the branches (components) together in a consecutive string so that the current flowing in one must be the same as the next. In this case then the voltage must be different across each component if the R of each component is different.

What is formed around a wire when electricity flows through it?

Current through a conductor forms a magnetic field.The "Right Hand Rule" will tell you the direction: Point the thumb of your right hand along the conductor in the direction of current flow (from negative to positive) and the fingers of the right hand curl in the direction of the magnetic field force lines.


What is the magnet formed by the flow of electric current?

When electric current flows, a magnetic field is formed via induction. When copper wire, or another conductor is wrapped around a metal core, it forms an electromagnet.


What is difference between an insulator and a electromagnet?

Electromagnet is a type of magnet formed when current flows through a conductor or coil thus producing a magnetic around it. The magnetic properties are only present as long as the current is flowing through such a wire or coil. Insulator is any material that offer exceptionally very high resistance to the flow of current.


Why does electricity produce magnetic field?

It is just one of the properties of matter that when an electric current passes through a conductor a magnetic field is formed around the conductor. Why this happens I don't think anyone knows.


How can current only be formed?

Compass needle move when a current switched on?

this is because of magnetic field formed when the current flows through it. this is called electromagnetism. if we move the compass needle away from current carrying conductor or wire it returns to its position (north south position)


If a conductor carrying an alternating current is formed into a coil the magnetic field that is generated?

If the current is alternating, the magnetic field will also be alternating.


Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?

The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.


If a conductor carrying an alternating current were formed into a coil the magnetic field that is generated?

Will cancel out and become zero


What is a current circuit?

A current circuit refers to a closed path through which electric current flows. It is formed by connecting various electrical components, such as resistors, capacitors, and inductors, with conducting wires. The current circuit allows the flow of electric charges, usually in the form of electrons, from the power source to the load.

How are electromagnets formed?

A magnet consisting essentially of a coil of insulated wire wrapped around a soft iron core that is magnetized only when current flows through the wire.
