How are capacitors used in speaker applications?
Capacitors are used to limit the frequencies sent to speaker units in multiple speaker applications. As the frequency increases, so does the effective resistance of the capaitor. (known as reactance) For instance, tweeters only work efficiently with high frequencies. Applying low frequencies to these devices is inefficient and could cause harm to the unit. Putting a capaitor in line with it will only allow high frequencies through. Using a combination of capacitors and coils, in parrallel to form filters, can make only desired frequencies pass to the correct driver unit. Each speaker can then work most effeciently with the desired frequency. This is a fine art, to make sure that the sound is pure and not coloured or distorted and has to also match the cabinet in which the drivers are mounted.
How capacitors have made advancement in technology?
It is fair to say that without capacitors (and resistors and inductors) we would have no electronics. Better dielectrics are an area for improvement in capacitors, as is reduction in size.
When you put two 10 µF capacitors in parallel the equivalent capacitance would be?
With capacitors in parallel you can just add the microfarads.
Do frequencies in the 28 GHz spectrum have 40x the capacity of frequencies in the 700 MHz spectrum all other things being equal?
The answer is no. What determines maximum channel capacity is spectrum width not absolute value. For example 700 - 720 MHz would have the same potential capacity as 28000 to 28,020 Mhz. 28,000 to 28,160 Mhz could potentially have 40 times. 700 Mhz is much better spectrum than 28 GHz because lower frequencies have lower attenuation rates and travel further with acceptable signal to noise ratio. Lower frequencies are also much better going through walls. That's why Verizon and others paid so much for it.
Why LC oscillator not suitable for audio frequency?
Another type of sine-wave generator uses inductors and capacitors for its frequency-determining network. This type is known as the LC OSCILLATOR. LC oscillators, which use tank circuits, are commonly used for the higher radio frequencies. They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
What would you measure capacity in?
Lots of things are measured in capacity. Many cars have a 13 or 21 gallon capacity. Drink manufacturers measure the capacity of the containers they are filling. Reactive (electrical) power is measured in capacitance. Capacitors have a measurable capacity of storing and releasing reactive power for voltage and load control. (Surges and dips).
Why voltage gain decreases at high frequency in case of a transformer coupled amplifier?
Depends on the elements used in the circuit.1.At Low frequency: The coupling capacitors are used to isolate the AC input and output from DC bias conditions for active devices. These capacitors with the input and output impedance of the active device act as a high pass RC filter, hence the gain falls.2. At High Frequency: The frequency is high, but not as high as the microwave frequencies. There are two reasonsa>The capacitance of connecting wires are connected in parallel the i/p and o/p. When a capacitor is connected in parallel it acts as low pass filter, hence the voltage gain falls. This is when the frequency is high but not high as microwave frequencies.b> The parasitic capacitance's of the active device are connected in parallel with the i/p and o/p terminals. They along with the device impedances act as low pass filter.
Would frequencies (Hz.)of the human body be religeous and spirituality frequencies?
No, that is completely unrelated.
Why does generally capacitors are in pico or nano farads not in kilo or mega farads?
Large value capacitors are difficult to make (large value inductors are even harder to make) and take up large volumes of space. One farad capacitors are available in electrolytics, but are about the size of soup cans. If they were made, kilo & mega farad electrolytic capacitors would have volumes of roughly a thousand & a million soup cans respectively! Nonelectrolytic capacitors would be far larger!!!
Differences between conductors and dielectrics discharge?
A pure conductor will conduct or pass AC or DC current/voltage reguardless of frequency. An example would be a piece of wire. A dialectric is usually associated with capacitors and is the material used between a capacitors plates. A capacitor will block pure DC current and will pass AC current. It works by storing a positive or negative charge of an ac signal and discharging the current back into the circuit as the charge begins to approach 0 or where it crosses over from positive to negative. In a bandpass/ban reject filter network it is use to pass certain frequencies and/or reject others. In a power supply it is used to convert ac to dc by smoothing out the "ripple" of the cycle of said frequency. To pass frequencies it is usually series or series/paralles in the circuit. As a filter for a power supply one side will usually go to ground. The latter is what your transformer you plug into your wall does for a device that uses dc voltage/current and also operates on batteries.
At what frequency does SETI listen at?
SETI listens to frequencies between 1420 (the Hydrogen molecule) and 1662 (the hydroxyl molecule). This is to say that an intelligent civilization would recognize these frequencies and would probably be monitoring them a well. The cosmos is full of these frequencies and a slight deviation in the regular pulsing of these frequencies would be noticed by anyone who is scanning the skies. Hope this helps. Sam Farina III
What are frequencies in maths?
Frequencies typically refer to counts, or "how many". If you wanted to know the frequencies of students in a school by gender, you would simply be asking about "how many" boys and how many girls there are.
