what is the difference between vector and phasor?
319942
A phasor is a rotating vector. Whereas a vector represents quantity and direction, a phasor represents quantity and displacement measured in a counterclockwise direction. Phasors are used in electrical engineering to represent certain AC quantities -e.g. the relationship between current and voltage.

In a DC generator, the electrical current flows only in one direction. In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less. In a DC generator, the coil through which the current flows rotates in a fixed field.

Key Differences between Active and Reactive Power The active power is the real power consumes by the load. ... Whereas, the reactive power is the product of voltage and current and the sine of the angle between them. The active power is the real power, and it is measured in watts.

Difference between synchronous generator and induction generator. In a synchronous generator, the waveform of generated voltage is synchronized with (directly corresponds to) the rotor speed. ... If an induction generator is meant to supply a standalone load, a capacitor bank needs to be connected to supply reactive power.

Vector is better for frequent insertion and deletion whereas Arrays are much better suited for frequent access of elements scenario. Vector occupies much more memory in exchange for the ability to manage storage and grow dynamically whereas Arrays are memory efficient data structure.

AMPS is amount of electricity. VOLTS is the Push, not the amount. OHMS slows the flow.

Key Differences between Active and Reactive Power The active power is the real power consumes by the load. Whereas, the reactive power is the useless power. ... Whereas, the reactive power is the product of voltage and current and the sine of the angle between them.

Uses & Design Differences An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. ... In contrast, the coil in a DC generator is not fixed; rather it rotates in a fixed field.

In a single-phase power supply, it only requires two wires, namely Phase and Neutral. On the other hand, a three-phase power supply only works through three wires, including three-conductor wires and a neutral wire.

In an inductive circuit, voltage drop across an inductor leads the current flowing through it by 90 degrees. We say that phase difference between both parameters is 90 degrees. The same can be seen in the phasor diagram shown.

What's the difference between the Vector 3 and the Vector 3S? The Vector 3 gives you feedback from both pedal while the Vector 3S provides data from only one. Receiving information from both pedals more accurately indicates how you use each side of your body to power the bike.

The difference between asynchronous and synchronous generator. A synchronous generator is called “synchronous” because the waveform of the generated voltage is synchronized with the rotation of the generator. ... An asynchronous generator is essentially the same machine as an asynchronous or induction motor.

Vectors. The key difference between Arrays and Vectors in Java is that Vectors are dynamically-allocated. They aren't declared to contain a type of variable; instead, each Vector contains a dynamic list of references to other objects. ... When a Vector is instantiated, it declares an object array of size initialCapacity.

The major difference is that synchronous motors develop a sinusoidal back EMF, as compared to a rectangular, or trapezoidal, back EMF for brushless DC motors. Both have stator created rotating magnetic fields producing torque in a magnetic rotor.

The main difference between synchronous generator and induction generator is the link between rotor speed and ac supply frequency generated by the machine. For a synchronous machine, the frequency is synchronous to the speed. ... For an induction machine, the frequency is not more proportional to the speed.

The difference is that in the case of a capacitive load, the current reaches its maximum value before the voltage does. The current waveform leads the voltage waveform, but in an inductive load, the current waveform lags it.

What is the difference between a scalar and vector? A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. ... Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude. The speed is the magnitude of the velocity.
