I just finished building my PC like a week ago. I just noticed there is a faint buzzing noise while playing a game (the noise also comes out from my speakers). I tried to pinpoint the noise and turns out it's coming from inside my computer.
The buzzing noise sounds like it's coming from either power supply or graphic card.
please i want a power supply circuit its input 220v ac
and out 24v dc and 5v dc by using lm7824 and 7805
i want a stable power supply because it will be connected with
other appliance in home and there is high noise
I have to calculate the ripple voltage of four different capacitors in a power supply. the power supply is a transformer, bridge rectifier, load resistor and capacitor would go across the load.
I used multisim to simulate the circuit. I looked at the ripple which has a peak to peak value.
my question is, to get the mean dc value, what is the formula for this.
