What is meant by frequency in motor?
In the context of motors, frequency refers to the number of cycles of alternating current (AC) that occur per second, measured in hertz (Hz). It directly influences the speed of the motor; for instance, in synchronous motors, the speed is proportional to the frequency of the AC supply. Higher frequencies typically result in faster motor speeds, while lower frequencies decrease the speed. Understanding frequency is crucial for ensuring the motor operates efficiently within its designed parameters.
What are the advantages of FSK?
-> frequency shift keying promotes long distance communication. ->it has high security. ->low noise ->efficiency is high. ->decoding of signal is easy.
When you rotate the handle of the electric generator faster does it deliver more less or the same voltage?
The speed of a generator only effects the frequency. Most generators operate at 1800 RPM. The output voltage is controlled by varying the field excitation voltage.
Why a given generator frequency is dictated by the size of the magnetic flux?
A generator's frequency is dictated by the power system frequency, and the number of poles in the generator. For 60 Hz power and a generator designed with two poles, the generator must turn at 3600RMPs (60 Hz * 60 seconds / minute). The magnetic flux is what induces the current in on the output winding. Spinning a synchronous generator faster or slower is not done to control the magnetic flux. The field winding voltage is varied to control this, and in turn control the output of the generator.
Why scope frequency is always greater then signal frequency in the oscilloscope?
In the course of sampling a signal to graph the parts of a repeating event on the display, the sampling must be done faster than the event you want to graph. If the sampling is done slower than the event then you will be displaying several parts of the event in a single dot on the display, highly inaccurate. The signal sampling must be done fast enough to display the event in enough detail. The higher you set the scope frequency, the wider the event appears on the display, possibly losing the sides of the event if you go too high.
Is wireless networking faster than traditional networking configuration?
Depends on your wireless protocol vs your physical port speed. But typically, a wired connection is best if connecting to the same router.
What travels faster short or long wavelength?
Short wavelengths travel faster than long wavelengths. This is because light travels at a constant speed, and since wavelength is inversely related to frequency (shorter wavelength means higher frequency), shorter wavelengths have higher frequencies and thus travel faster.
Which 802 project standard defines wireless at speeds of 54 Mbps and a frequency range of 2.4 GHz?
The 802.11g standard defines wireless networking at speeds of up to 54 Mbps and operates in the 2.4 GHz frequency range. It was developed as an enhancement to the earlier 802.11b standard, providing higher data rates while maintaining backward compatibility. 802.11g is widely used for wireless local area networks (WLANs) and supports various applications requiring faster data transmission.
If you make a musical instrument shortter will it have a high or low frequency?
That would surely depend on the specific instrument, and the way it produces its sound. Two examples:A shorter string will vibrate faster, and therefore produce a higher frequency.Similarly, the air in a shorter tube will vibrate faster, and therefore produce a higher frequency.
What is faster red or violet light?
Violet light is faster than red light because violet light has a shorter wavelength and higher frequency, allowing it to travel faster through a medium.
Why very low frequency is having no use for data transfer in computer network?
Low frequency devices are losing popularity in computer networking because of their slow transfer rates. The higher the frequency of a device the faster it can transfer data.
What is faster LAN or Wireless?
LAN is a collection of computers with in certain distance say, a building or premises or within a city. A LAN can be a collection of wired computers or wireless computers or mixed. A wireless connection is a connection which uses radio frequencies to send and receive data, e.g. a mobile phone is an application based on wireless connection.
Why do shorter tubes produce higher pitch sound?
Shorter tubes produce higher pitch sounds because they have a shorter length for the sound wave to travel through, resulting in a higher frequency of vibrations. This faster vibration rate creates a higher pitch sound compared to longer tubes which have a lower frequency.
Which is more faster wired Internet or wireless Internet and why?
Wired internet is faster as it works in full duplex mode (can send and receive at a time). Wireless works using half duplex mode, requires a middle device (like access point) for transmission and various other factors like devices using the same radio signal frequency (2.4 GHz) affect its transmission
Why does the frequency of a pendulum move faster if you shorten the string?
Shortening the string of a pendulum decreases the distance it needs to travel, resulting in a shorter period for each swing. Since frequency is the number of swings per unit of time, shortening the pendulum causes it to move faster.
What happens to the wave when you decrease the wave period?
When you decrease the wave period, the wavelength becomes shorter and the frequency increases. This results in the wave moving faster.
Why does a higher frequency wave have more energy?
A higher frequency wave has more energy because energy is directly proportional to frequency in waves. Higher frequency waves have shorter wavelengths and more oscillations per unit time, which requires more energy to sustain the faster oscillations.
