Kenn3th,
i got a very basic pc recently with a very low-power
cpu.............i don't do any gaming at all............
i read your article on quality of power supply so i'm thinking
if it's possible to improve ac quality to the power supply
by.............
## getting a better power cord for the
computer........(works for audio systems leh)
## use ferrite rings around the power
cord....................
From my own point of view, a better power cord will surely
make you feel safer and more confident while computing.
And from an electronics engineering point of view, a thicker
powercord may mean less resistance as the total area of the wire is
increased.
The previous sentence is applicable if the wire you bought is
genuinely thicker in terms of the conductor instead of the
insulator, and if the wire inside the power cord is a single solid
strand.
This is based on the formula for calculating resistance for
wire, which is Resistance = (Resistivity of the wire * Length) /
Area of the wire.
So if the area increase, the resistance DECREASES. And if the
length increases, the resistance INCREASES.*
However, again, the powercord is connected from the mains to
your power supply.
Depending on how you see it, lower resistance may it can take
more current, and may be a good thing if you are using a high power
powersupply.
-------
Ferrite rings are used to filter out high frequency noise
signal. Ferrite rings is a coil of wires, which is something like
an inductor.
The formula for calculating inductance(which is the
impedance(which actually means the resistance) of the inductor) is
Resistance = 2 * pi * Frequency * Inductance.
So when higher frequency signals
reaches the inductor, it sees it as a path with very high
resistance, and thus less likely to flow through, (Because
based on the formula, the higher the freq, the higher the
resistance) but when low frequency
reaches the inductor, and based on the formula, it sees it as a
path of low resistance, and thus more likely to flow
through.*
When a circuit allows low
frequency to pass through but attenuates high frequency to pass
through, it is called a low pass filter.
Therefore, ferrite rings can be said to be used as a low pass
filter to filter out(the correct word is attenuate) high
frequency(which is sometimes considered as noise) noise from the
circuit, thus reducing the risk of errors caused by noise.
