Why DC electricity does not have poly phase?

There is no such thing as phase in DC as phase requires AC. To have two or more things out of phase requires them to be changing. Only AC does that. DC is steady state.


Why you prefer three phase AC and single phase DC for transmission?

3-phase ac is commonly used for transmission over several hundred kilometres within a synchronous grid system. DC is used for longer distances or for connection between two systems which are not in synchronism.


What is the difference between in ac and dc powwer cable?

There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.


How AC analysis differs from DC analysis?

You need to keep track of phase angle in AC, but not in DC.

Why dc voltage increased less rapidly as the dc current increases at three phase alternator?

if you mean in your question Why the generated voltage (AC voltage) increased less rapidly as the dc current increases at three phase alternator? the answer is: because the magntic material that used in the 3 phase alternator will reach to satruration case of producing the magnatic flux so will happen a knee saturation curve in (I dc) versus (E ac) curve.

Can you represents three phase ac with positive and negative?

AC is normally referred to as active and neutral, while DC is referred to as positive and negative. "Can you represents three phase ac?" not sure what you mean here. Each of the three phases are active ( positive ) so you could not represent one of them with negative. Hope this helps.


How do you change the connection of single line to 3 phase line of DC motor?

To change the connection of a single-phase line to a three-phase line for a DC motor, typically you would need to use a phase converter or a variable frequency drive (VFD) to convert the power supply. This will allow you to provide the necessary three-phase power to the DC motor for it to operate efficiently and safely. It's important to consult with an electrician or engineer to ensure the proper conversion is done based on the motor specifications.


What is the theory of conversion of AC to DC using 3-phase induction motor and DC shunt generator?

The theory of converting AC to DC using a 3-phase induction motor and a DC shunt generator involves utilizing the induction motor to mechanically drive the shunt generator. When the induction motor is powered by a three-phase AC supply, it operates and drives the rotor of the connected DC shunt generator. This generator then converts the mechanical energy into electrical energy, producing a DC output. The process allows for efficient conversion of AC to DC, leveraging the motor's mechanical properties and the generator's electrical characteristics.


Is there such a thing as 115V 3 phase?

No!The concept of three phase alternating electricity refers to the relational phase differential of three alternating current single phase sine waves, each displaced 120 degrees of phase angle from the other.Addetion:still the is a three wire DC transmission system.usually DC transmission used for several resone but the most know one is when the transmission line is longer than 600 km


Does an inductor work in both ac and dc?

Depends on what you mean by work. It still opposes changes in the current flow through it, that doesn't change. But as DC has no phase, it produces no phase shifts as it does in AC.
