How many wire or core in three phase electrical connection and single-phase electrical connection?

A single-phase cable will have a line and a neutral conductor and, possibly, but not necessarily, an earth (ground) conductor.
A high-voltage three-phase cable will have three line conductors. A low-voltage three-phase cable is likely to have three line conductors and a neutral conductor.

What is a wye?
A wye connection referring to electrical connections is where one end of the three coils of a three phase system are joined together and usually grounded. The three phase supply voltage is then connected to the other ends of these coils. In electrical terminology it is also known as a star connection.
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
What is 1.73 in load current calculation?
1.73 (the square-root of 3) is the ratio of line voltage to phase voltage in a star (wye) three-phase connection, and is the ratio of line to phase current ratio in a delta three-phase connection supplying a balanced load. In each case, it is derived from the phasor addition of two values displaced from each other by 120 electrical degrees.
Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
What is single phase ac generator?
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
How do you fix a three-way electrical connection?
Could you be a little more specific please. Are you refering to a three phase supply or something like a three-way connection to an outlet or a light????

Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
What is mean by 7segment distribution board?
A distribution board which has 7 segments , one for Main incomer, three as sub incomer for each phase and three for singlephase outgoing is called a 7 segment DB
What type of connection do you use in household connections?
its simple: its either single phase or three phase connection

Advantages of scott connection?
to convert three phase to two phase and vice versa
What is the electrical engineering 3 phase?
The electrical engineering 3 phase is calculated by mathematics. The total active power is equivalent to three times the power of an individual phase.
What cannot be considered a single phase?
Any load that needs three legs from a three phase system can not be considered single phase. Single phase from a three phase system only needs a connection to two legs.
What is The Connection in three phase transformer?
the connection here meant for the connection of windings in three core or limbs of a transformer. it might be delta or star connected.
What is single phase ac generator?
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
