What is multiplex winding?
a wave winding in which the number of parallel circuits is a multiple of two, other than four, whatever the number of poles
How a current relay operates to remove the start winding from the circuit?
A current relay operates by monitoring the current flowing through the start winding of a motor. When the motor reaches a predetermined speed, the current in the start winding decreases. This drop in current activates the relay, which opens its contacts and disconnects the start winding from the circuit, allowing the motor to run efficiently on the run winding alone. This process helps prevent overheating and damage to the start winding.
how a start capacitor start winding in series affect a motor?
A start capacitor in series with the start winding of a motor enhances its starting torque by creating a phase shift in the current flowing through the start winding. This phase shift generates a rotating magnetic field that helps the motor overcome inertia and start more efficiently. Once the motor reaches a certain speed, a centrifugal switch typically disconnects the start capacitor and winding, allowing the motor to operate on its main winding alone. This design improves the overall performance and reliability of single-phase induction motors.
Why armature winding resistance is less than field winding resistance?
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.
Definition of a resistance-start induction run motor?
Resistance start-induction run motors are commonly known as split phase. They are only single phase motors. They have 2 sets of windings, the Start winding which is high resistance and low inductance made for thin wire, and the Run winding which is low resistance and high inductance made for thick wire. The 2 windings are set skewed about 30 degrees on a twist. This is to create the angular rotary motion, which is what a motor is all about. On start up both start and run windings are energised. Some form of switch disconnects the start winding when the motor is about 75% up to speed, and only the run winding remains in the circuit. There you have it.....
Why the capacitor motor will not develop any starting torque without capacitor?
The start winding needs a capacitor in series with it in order to produce a phase shifted magnetic field that will develop the torque necessary to bring the rotor up to operating speed. Once operating speed it obtained, a centrifugal switch opens and disconnects the start winding - the rotor's inertia can then keep it going as needed.

A current relay operates by monitoring the current flowing through the start winding of a motor. When the motor reaches a predetermined speed, the current in the start winding decreases.

What is a balance order?
An order obtained by a liquidator making a call on contributories in the course of the winding up of a company.
How do you connect capacitor to a capacitor start motor?
A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.
What rotates to create electricity?
a rotor which is powered with a dc voltage using a commutator turns within a stator winding system, and the created magnetic field cuts through the stator windings and induces a voltage into the electrical winding circuits.

What is tertiary winding of a transformer?
A third winding - primary, secondary, and tertiary. The third winding is typically sized much smaller than the primary and secondary, and is very often a lower voltage; it can be used for stabilization, removal of 3rd harmonics, power factor correction injection (lower voltage inductors are cheaper), and station service.
What happens if a dc supply is given to a transformer under no load?
when dc supply is given to transformer at primary winding , the output at secondary winding will be zero.Because to induce voltage ,countnie changing flux is required ,that can not be obtained from dc supply...........
What electrical test instrument is used to measure continuity in a compressor winding?
A digital multimeter (DMM) is commonly used to measure continuity in a compressor winding. By setting the multimeter to the continuity test mode, it can check for a complete electrical path in the winding. If the circuit is intact, the multimeter will emit a beep or display a low resistance value, indicating good continuity. This test helps identify any open circuits or faults in the winding.
Why a two winding transformer is used instead of single winding transformer?
You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.
What is the function of a primary windding?
I assume we're talking about transformers here. The primary winding carries the input (alternating) current to the transformer. The (alternating) magnetic field it generates passes through the secondary winding and induces an (alternating) voltage in that which can be uses to power up other circuits.
