# How long does it take to reduce the capacitor’s charge to 10 μc?

The capacitor is a device that stores electric charges. A capacitor consists of two conductors separated by an insulating material called a dielectric. When the voltage between the conductors exceeds the breakdown voltage of the dielectric, current flows in a path from one conductor to the other and charges up both plates equally.

In this article, you will find out how long it takes for energy stored in a capacitor to drop 10 μc and what affects how fast it does so!

How much time does it take to reduce the capacitor’s charge by only ten micro coulombs? A capacitor consists of two conductors separated by an insulating material called a dielectric. When the voltage between these plates exceeds its breakdown or maximum sustainable value, then-current flows in a path from one plate to the other and charges up both equally. So how long do we need for this process to happen for our instance of twenty μc being reduced down to only ten μc? The answer is approximately half a second! This is because capacitors have what is referred to as charging times that depend on their capacity (or amount) and type. Now let us consider why it takes so long: there are five main factors that contribute to how long it takes for a capacitor’s charge to reduce, but in this blog post I will only mention two of them. The first is the resistivity of the insulating material (in our case air), and the second is termed capacitance which can depend on many different things such as the surface area or size of one plate relative to another (or in general)

Charge: Charge refers to the quantity of electric potential difference between two points within an electric field. It is usually measured by coulombs per volt. In capacitors it would be electrons because they are negative (-) while protons (+) are positive(+).

Capacitance: the capacitive property of a capacitor is its ability to store charge at an electric potential difference. The more capacity or storage, the larger the size of one plate relative to another (or in general) and so it can be measured as to how much charge per unit voltage, but because our capacitors are just air, they won’t have any significant amount of capacitance. It will take a little bit longer for your nether portal’s energy field to reduce by ten μc from 1000μc than if you had two plates connected by metal wire coiled around them which would lower their resistance and allow for a larger voltage difference, and so the energy would move across them at a quicker rate.

Capacitors: how capacitors work? in electronics circuits- they store electrical charge to use later on as needed. Our capacitor is an air capacitor that has no charge when uncharged but will accumulate more electrons with each discharge cycle while we wait for our nether portal’s field of 1000μc (a coulomb) to reduce by ten μcs (another Coulomb). The charge can be measured using something called Farads where if you have one amp going through your wire and there are two volts that created it, then the total resistance equals 2000Ωs because electricity dissipates over time and increases the distance from the source.

In this post, we are going to calculate how long it will take for the capacitor charge to reduce by ten micro coulombs (μcs). The first thing that you need to do is find out how many μCs there are in one coulomb. One Coulomb is equal to 1000 μC so a reduction of ten units would be 100 µC. We then have two options when looking at how much time it takes: either divide or multiply and use your answer as the number of seconds required.

## If we decide on multiplying, our equation looks like this:

100 x 3600 = 3600000  seconds per minute  x 60 minutes per hour

3600000/60= 6000 minutes which equals

12 hours

12 x 60 seconds in one minute = 720  seconds per hour

720/3600= 0.0167 minutes which is about 20 seconds. To simplify the equation, we can take it down to 100×60=6000 and 6000/60=100 so the answer would be 12 hours on average for a ten micro coulomb reduction of charge with a first-year lifespan or 120 milliseconds if you’re using an electrolytic capacitor that lasts six months.

However, this is not how long it takes for all capacitors to drop their charge by ten units as some will take longer than others based on many different factors such as temperature, age (the older they are the less efficient), amount of stored energy (the more energy in the capacitor, the longer it will take to drop its charge), etc. ## By Devesh Rai
