6 FAQs about [Capacitor output voltage impact]
What happens if a DC power supply has a capacitor?
DC power supplies can have a certain amount of ripple, spikes, and noise in their outputs. If you have only a capacitor without any load on the output, then the capacitor will eventually charge up the the maximum, or peak value, of the ripple, spikes, and noise.
What happens if you increase capacitor size to 100 UF?
Observations (using a 5 V peak AC signal input): If I increased the capacitor size to 100 uF and leave the resistor fixed, I get a smoother (more DC-like) voltage. However the value of this smoother DC is now 4.1 V, which I find strange. Shouldn't this DC voltage be exactly the same as the 4.4 V peak that was obtained using the 1 uF capacitor?
How are output capacitors chosen?
