Why would a capacitor connected to a pwm output "average"
Really straightforward question, not related to any projects, but its been bugging me for a while. Say, I set up an arduino pin with 50% PWM frequency, which basically means keeping the input on half the time and off the other half. which in turn turns an LED at 50% brightness. pretty basic stuff. BUT. add a parallel capacitor with the led, it averages the
What will happen if we connect capacitor and battery directly?
No surprise there – take an ideal source of power and connect it to an ideal sink of power, and the power flow will be infinite. The energy stored in the capacitor would be half of the work done by the battery (as per general relations of capacitor.) No, it would be the same as the work done by the battery.

Incorrectly Using Capacitors
The voltage on a capacitor is not the rating, but rather how much voltage you can expose the capacitor to. For example, if your voltage source is 9 volts, you should choose a capacitor that is at least double the voltage, 18 volts or even 27 volts to be safe. AC or bipolar electrolytic capacitors have two anodes connected in reverse polarity

Exploding Capacitor: Wrong Polarity & LED Damage?
Polarity refers to the direction of electrical flow in a circuit. Capacitors are designed to be connected in a specific polarity, and when they are connected in the wrong polarity, it can cause a buildup of excess energy and heat, leading to an explosion. What happens to an LED when a capacitor explodes due to wrong polarity?
What happens when capacitor is connected in series and parallel?
As the capacitance of a capacitor is equal to the ratio of the stored charge to the potential difference across its plates, giving: C = Q/V, thus V = Q/C as Q is constant across all series connected capacitors, therefore the individual voltage drops across each capacitor is determined by its its capacitance value.

What would happen with capacitors on headphones?
Working with a Klipsch Image S3 which has 18 ohms I put a couple of 150uF tantalum capacitors connected "anti-series" as mentioned before to create a non-polarized capacitor essentially of the average of the two (so much easier to do the math when only working with two.) That makes for about 75uF for a high-pass filter beginning at about 118Hz.

6 FAQs about [What will happen if the capacitor is connected incorrectly ]
What happens if you put a capacitor in the wrong way?
Circuit malfunction: If you put the capacitor in the wrong way in circuits like power supplies or audio amplifiers, you can get big voltage spikes, the signal can get messed up, or you can break other parts. In things like power supplies, if you get the polarity wrong, you can get power surges or the voltage won’t be regulated right.
What factors should you consider when using capacitors?
One important factor to consider when using capacitors is their polarity. Polarized capacitors have a positive and negative terminal, and must be connected to a circuit in the correct polarity. If a polarized capacitor is connected in the wrong polarity, it can be damaged or even explode.
Can a polarized capacitor explode?
Polarized capacitors have a positive and negative terminal, and must be connected to a circuit in the correct polarity. If a polarized capacitor is connected in the wrong polarity, it can be damaged or even explode. Non-polarized capacitors do not have a positive or negative terminal and can be connected to a circuit in any polarity.
What happens if you put polarized capacitors in the wrong way?
Polarized capacitors, like electrolytic, tantalum, and supercapacitors, have to be put in the right way so the positive and negative parts are in the right spots. If you put these capacitors in the wrong way, they can get too hot, break, or even blow up.
