Missing Capacitors, but "Shuttle XPC SG45H7" works fine. Side …
Say understanding why the capacitors were there, understanding if they are/were in parallel or meant to serve a single phase, understanding how much uF a missing condenser should be w/o having a friend that send a photo, could be a very nice piece of "useless" info.
capacitor
So the peak resistor voltage is about 10 volts, the peak capacitor voltage is about 2.9 volts, and the phase difference between the two voltages is exactly 90 degrees. The reason for the phase difference is that the capacitor voltage is always 90 degrees out of phase with its current, while the resistor voltage is always in phase with its current.

Two capacitor paradox
The two capacitor paradox or capacitor paradox is a paradox, or counterintuitive thought experiment, in electric circuit theory. [1] [2] The thought experiment is usually described as follows: Circuit of the paradox, showing initial voltages before the switch is closed. Two identical capacitors are connected in parallel with an open switch between them. One of the capacitors …
A/C Fan won''t turn on outside after replacing capacitor
The fan was damaged by the previous bad capacitor, ran for a bit, but now won''t even start with a good capacitor; The new capacitor was just a dud and failed almost immediately; If you had a multimeter, you could check the capacitor and also check the resistance of the fan motor windings as additional troubleshooting steps.
Chapter 5 Capacitance and Dielectrics
0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of separation because the smaller the value of d, the smaller the potential difference …
[SOLVED]
I can clearly tell the capacitor is missing and it doesn''t just look like its been knocked off, the pins of the capacitor are absent on the back of the motherboard and the little holes are soldered shut (excuse my lack of professional terms). It almost looks as if it has been deliberately removed but I can''t be sure.

Why Are Capacitors Used in Motherboards? (Explained)
Capacitors on different power circuits need different capacitance ranges and voltage ratings, which explains why the capacitors on a motherboard also vary in appearance. The more fluctuations there are on a circuit, the higher the capacitance range should be.
Why does there seem to be a missing component in many PCBs?
The transformer has been replaced by either a capacitor or transient suppressor. Note that the capacitor lies within the outline of the transformer - indicating the designer fully intended it would be an either/or design. Now, the PCB is also single-sided. This is the most popular choice for consumer products due to it being the lowest cost.
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. Initially

The resistance of the resistor is missing. The switch is closed at time t = 0. Find the initial current just after the switch is closed (t = 0+). What are the final values of the charges on the capacitors? Consider the circuit shown in the figure: Initially, the capacitor C is …
Why does the distance between the plates of a capacitor affect …
If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the attraction is stronger the closer they are. If the distance becomes too large the charges don''t feel each other''s presence anymore; the electric field is too weak.
Question Two tiny capacitors/resistors missing need help
If traces are cut (by missing capacitors there) in middle of first PCIe x4 group then probability that board detection will fail, is very real. This is why guys who want to make board PCIe bus "shorter", put isolation tape over specified unused PCIe connector contacts of whole PCIe group(s). Upvote 0 Downvote.
Where Does the Missing Energy Go When Capacitors are

How We Found the Missing Memristor
For nearly 150 years, the known fundamental passive circuit elements were limited to the capacitor (discovered in 1745), the resistor (1827), and the inductor (1831).
voltage
Now the capacitor can start at 0V, because V1 can appear across R to satisfy KVL. However, you must now additionally calculate energy lost in the resistor as the capacitor charges. You will find the "missing" energy has been lost as heat in the resistor. The value of the resistor does not matter.
