So far we've only seen circuits that allow a single path for electricity to flow-but it doesn't HAVE to! Here's a picture of what we call a parallel circuit. See how there's one power source and two electrical devices?Conductor wires connect the battery to each bulb independently.
Since the electricity can either go into the first bulb and light it up, or on to the next bulb and light that one . . . it does both! Some electricity flows to each bulb, distributing the power equally to both. So parallel circuits have more than one path for electricity to follow!

How do you conduct an insulation resistance test?
(1)make the transformer R,Y,B,N terminals in GST mode. (2)coneect insulation resistor test set to any of phase. (3)apply high voltage to that connected phase (4)test set will denote u the value of IR
What is the difference between PSK and QPSK?
in psk,we use only single type of phase shift for a bit transition. in qpsk,we use 4 types of phase shifts for a bit transition.
What is single transformation?
Single-phase electric power refers to the distribution of electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors.Do you know that there is a proposed 800-mile high-voltage direct current transmission line from Oklahoma to Tennessee?Read more about it by clicking on the link.AnswerA single-phase transformer is a simple transformer which will either step up, or step down, a single-phase voltage. A single-phase supply is a two-conductor alternating-current system, comprising a line conductor and a neutral conductor.As most high-voltage electrical distribution systems are three-phase systems, comprising three line conductors, a single phase distribution transformer's primary (high voltage) winding is connected between any two of the three high-voltage line conductors. As far as the secondary (low voltage) winding is concerned:in Europe, one end of the winding is earthed and provides the neutral terminal , while the opposite end provides the line terminal (L)in North America, the winding is centre tapped and grounded, providing the neutral terminal, while opposite ends of the winding provide the line terminals L1 and L2
Why do you use capacitors on fan motors or blowers?
We use capacitor on fan motor or blower to create phase difference between two winding(Starting & running). This phase difference introduce starting torque on fan motor. Otherwise without capacitor the torque produced in positive Half cycle of AC supply is nullify by the torque produced in negative half cycle.
What is the basic assumption inherent in Darcy's law?
incompressible fluid laminar viscous flow non reactive fluid single phase
How do you check single phase motor winding?
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
Is 3 phase motor run on 1 phase supply?
No. That would be a single phase motor.
What is the difference between a one phase and a three phase motor. And if a three phase motor is given a single phase supply will it run or not?
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.
How do you convert a 0.37kw 4 pole 3 phase motor to single phase?
The motor cannot be altered to work on single phase power. You will either have to put in a new single phase motor or use a phase convertor box. Do a google search for phase convertor - you will find plenty.
You have one hp three phase motor where as available power supply is only single phase how can you run this motor?
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
Load test on 3 phase induction motor?
When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
How do you reverse single phase ac motor to generator?
how reversing an ac single phase induction motor to wark as induction generator
How do you connected 3 phase motor to single phase power?
Use VFD to make 3 phase from single phase source.
What motor is used in a fan?
Single phase Induction motor
How Do You Rewind a single phase 100-220 motor?

Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
