Why would a capacitor connected to a pwm output "average"
As i understand capacitors, wouldnt it be charged with each rising edge of the pwm frequency? which also means the capacitor is charged with the peak voltage. Yes, the voltage does fall on the other half of the pwm. But still, the capacitor is charged with 5V, so basically it would give a rough sawtooth voltage.

Cooling Fan (12V/0.18A) with capacitor connection
Actually, in early i was thought the b) connection can be work for speaker, so i used a cooling fan instead. Normally we connect a capacitor in parallel with load to stablish the voltage supply. Since the cap are connects in series in between the VDD and load, so i thought it have an isolation function between the VDD and the load there.
swapped herm and fan on capacitor
Now that is over 100 degrees my AC can''t keep up. I had a technician out yesterday and he said the compressor wasn''t staying on and I need a new capacitor. I said hey I already fell for this $ cap trick last year (it is a $ part). I said maybe I will just replace it myself. He told me C is orange wire, HERM is yellow wire, and FAN is brown wire.
CAPACITORS AND FANS WITHIN UPS SYSTEMS
WHY YOU SHOULD REPLACE THE CAPACITOR EVEN IF THE UPS IS STILL WORKING When an individual capacitor fails, it is often a sign that the other capacitors may also be under stress. There may be obvious signs such as leakages and splits, but a visible inspection would not reveal that any capacitors may have failed in the "open" condition.

6 FAQs about [Why should the fan be connected to a capacitor ]
Why does a fan need a capacitor?
The capacitor helps the fan motor to control the inertia of the fan blades and causes them to move, helping the fan to start fast and smoothly. If there is no capacitor, the fan can face difficulty starting or also stall, causing damage. The capacitor protects the fan motor and other parts of the fan from getting damaged.
What is a capacitor in a ceiling fan?
A capacitor is an electrical device that stores electrical energy in an electrostatic field. In ceiling fans, capacitors serve two primary functions: 1. Power Factor Correction: Ceiling fans consume both active power (used to rotate the blades) and reactive power (used to create the magnetic field in the motor).
What is the difference between a capacitor and a fan motor?
Motor Running: The capacitor keeps the fan motor going once it starts, and fan capacitors increase motor performance and efficiency. Fan single-phase induction motors keep the capacitor linked to the auxiliary winding after starting. This phase shift keeps the magnetic field spinning and the motor running smoothly.
How to connect a capacitor with a ceiling fan?
So we can get an idea about how to connect a capacitor with a ceiling fan. Generally, in the ceiling fan, there are two windings running winding & starting winding. A capacitor must be connected to the starting winding in series after that, it must be connected across the power supply.
What happens if a capacitor is not connected to a ceiling fan?
If the capacitor is not connected to the ceiling fan, it will not work accurately. The capacitor is the main component of the ceiling fan since it helps to control the speed of the fan. Without a capacitor, the fan does not start or work at different speeds.
What is the capacitance of a fan motor?
The capacitance of a capacitor is measured in microfarads, and it defines the energy stored in a capacitor. The capacitance must be enough to offer the required starting torque for the fan motor. The normal range of fan motor capacitors is 5 μF to 50 μF. The voltage rating of the capacitor must be according to the voltage supply of the motor.
