given a balance three phase, three wires system with star-connected load for which lime voltage is 230v and the impedance of each phase is (6+j8)ohm. find the line current and power absorbed by each phase.
Yes, there a difference between three phase and single phase electrical supply services.
The power factor is a measure of the phase difference. If they are exactly in phase the PF = 1. If they are 180 degrees out of phase PF = 0.
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
One uses single phase AC current (120/240), the other uses 3 phase AC current (most households will not have 3 phase in their home) One uses a 3 phase motor the other a single phase motor. 3 phase is usually used in industrial applications while single phase is used in home or small business apps.
If, by 'unit price', you mean the cost per kilowatt hour, then there is normally no difference between the cost of energy supplied whether by single-phase or three-phase supplies.
Yes, there a difference between three phase and single phase electrical supply services.
Yes, there is a difference between single phase and three phase circuits.
All current is the passage of electric charges from one terminal to another through a conductor so there is no real difference in the type of current that flows in a 3 phase system compared to a single phase system.
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
The power factor is a measure of the phase difference. If they are exactly in phase the PF = 1. If they are 180 degrees out of phase PF = 0.

actually there is no difference between them. However in some counteries, single phase is used for domestic and three phase is used for industrial.
Power factor measures the phase difference between voltage and current. If they are in phase the Power Factor is one. If the current and voltage are out of phase the power factor is between zero and one. You can describe the PF by saying the current lags the voltage with a PF = .8 or the voltage leads the current with a .8 PF.
the purpose of the capacitor is to create a phase difference between main winding current and axillary winding. this would produce a rotating constant magnetic field which is required to produce the torque.
One uses single phase AC current (120/240), the other uses 3 phase AC current (most households will not have 3 phase in their home) One uses a 3 phase motor the other a single phase motor. 3 phase is usually used in industrial applications while single phase is used in home or small business apps.
1) in inductor there is generation of magnetic field due to flow of current . so there is phase difference in voltage and current . 2)in capacitor there is storage of charges. there is phase diff. 3)But in case of resistor there is no such things are happend . it is only a power dissipating element.therefor there is no phase difference between current and voltage.
because of the reactances in the circuit
