Capacitors of the same capacity have higher voltage
Difference between capacitors of same value but different sizes
Also, bigger capacitors will usually have higher voltage rating, they cool down better. It also might be age (caps get smaller with years) or manufacturing capabilities. For example of the latter: if you were to buy strictly "Made in Russia" parts, you''d have to
Can I Replace a Capacitor With a Higher µF? | Is It Possible to Do?
How Can I Replace a Capacitor With a Higher µF? Whether a capacitor can or cannot be replaced by a higher µF depends entirely upon the function of the capacitor in the circuit. The function of a capacitor in a circuit can be divided into two classes roughly. If the capacitor is used just as a charge storage device or if its capacitance affects the circuit.

High-voltage capacitor in a low-voltage system
While not a perfect analogy, think of the voltage on the capacitor similar to the liter capacity of a tank. It will hold "35 V" but you needn''t fill it completely. But like @JustJeff said, you''d be wise to ensure the container can hold more than necessary to prevent spills ...

Ultracapacitors and the Ultracapacitor Battery
Where: Q (Charge, in Coulombs) = C (Capacitance, in Farads) times V (Voltage, in Volts) The unit of capacitance is the coulomb/volt, which is also called the Farad (F) [named after M. Faraday] with one farad being defined as the capacitance of a capacitor, which requires a charge of 1 coulomb to establish a potential difference of 1 volt between its two plates.
Why does the voltage increase when capacitor plates are …
In lab, my TA charged a large circular parallel plate capacitor to some voltage. She then disconnected the power supply and used a electrometer to read the voltage (about 10V). She then pulled the plates apart and to my surprise, I saw that the voltage increased ...
19.5: Capacitors and Dielectrics
The capacitor stores the same charge for a smaller voltage, implying that it has a larger capacitance because of the dielectric. Another way to understand how a dielectric …
What Happens if You Use the Wrong Size Capacitor? Is It Safe?
The difference in capacitor sizes may be big enough to restrict the expected accuracy if the capacitor is part of a tuned filter. If it is used to reduce ripple in a power circuit, this slightly higher capacitor size may have no effect and may even be an improvement. What
Chapter 5 Capacitance and Dielectrics
Capacitors have many important applications in electronics. Some examples include storing electric potential energy, delaying voltage changes when coupled with
Replacing Capacitors in Old Radios and TVs
Note that two of these types—mica capacitors and flat molded paper capacitors—look similar. Both are flat, often with color coding dots to indicate the value. It is easy to tell them apart by checking the value. Mica capacitors have very small values, typically under .001 mfd., typically under .001 mfd.
8.2: Capacitors and Capacitance
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. …
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.
8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …
Are capacity and capacitance the same?
Given two capacitors with the same voltage across them, the one with the higher capacitance will have more charge on it assuming that you don''t exceed the …
Are capacity and capacitance the same?
Given two capacitors with the same voltage across them, the one with the higher capacitance will have more charge on it assuming that you don''t exceed the voltage rating of either one. In this sense, capacitance can be thought of as "the capacity to hold charge"; a higher capacitance means more charge, all things being equal and assuming …
Series and Parallel Capacitors | Capacitors | Electronics …
If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors. As we''ve just seen, an increase in plate spacing, with all other factors unchanged, results in decreased capacitance.
Can capacitors be replaced with higher capacitance …
I have a bad capacitor on this LCD power board. I have rev 2.6, and I noticed there is a rev 2.8 board that looks like it didn''t get skimped on in parts. Can I install capacitors in my rev 2.6 board as they …
18.5 Capacitors and Dielectrics
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is …
Is it OK to Use a Higher Voltage Capacitor: Weighing the Pros …
Capacitors with higher voltage ratings have a higher tolerance for voltage spikes and transients, making them more robust and less prone to failure. Another advantage is increased capacitance. Higher voltage capacitors often have larger capacitance values, allowing for the storage of more energy.
Introduction to Capacitors, Capacitance and Charge
All capacitors have a maximum voltage rating and when selecting a capacitor consideration must be given to the amount of voltage to be applied across the capacitor. The maximum amount of voltage that can …

Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates.
Capacitors
When working with capacitors, it''s important to design your circuits with capacitors that have a much higher tolerance than the potentially highest voltage spike in your system. Here''s an excellent video from SparkFun Engineer Shawn about what happens to different types of capacitors when you fail to de-rate your capacitors and exceed their maximum …
