# How Long Does It Take To Reduce The Capacitor’s Charge To 10 μc (And Why)?

## Exact Answer: 7 Seconds

Science has been playing a very important role in every household for a long period. Most of the products that are found in a household are made with the help of science. Starting from electrical appliances like television, air conditioner, refrigerator to the paints that have been put up on the walls. Paints are made of chemicals that are part of chemistry. And chemistry being a part of science make it an invention of science.

Summary

Just like chemistry, physics is also a part of science. Physics comes from the word physical, deals with the properties and nature of energy and matter. The concept of a capacitor comes under physics. It can store electrical energy in them. It generally takes about 7 seconds to reduce its charge to 10 μc or 10 micro-coulombs.

## How Long Does It Take To Reduce The Capacitor’s Charge To 10 μc?

As mentioned above, it takes about 7 seconds to reduce the capacitor’s charge by 10 μc. In most cases the reduction in charge manually but sometimes it can do that automatically. A capacitor was previously called a condenser. It is used for storing energy electrostatically under an electrical field. It is a passive electrical component having two terminals. Practically, capacitors can be of different types but the concept remains the same in every one of them.

The capacitor has a minimum of two electrical plates which are separated by an insulator. The time to reduce the capacitor’s charge can be derived by mathematical procedures. By applying formulas it is very easy to know the time. To solve the problem, a person has to use an expression for potential difference across the discharging capacitor into the RC circuit to get the charge of the capacitor.

After getting the charge of the capacitor, the person has to convert the equation to get the charge, using the definition of capacitance. After solving, the final task is to put the values given in the equation and the person will get the answer. The answer will come around 7 seconds. It is very important to avoid any kind of calculation error as it may lead to wrong answers.

Capacitance is the effect that is made by the capacitor. Capacitors are mainly used in electronic circuits. It acts as a blocker for direct current while allowing the alternate current to pass through. They can be used to tune in radios and help the current to pass smoothly and stabilize the voltage.

## Why Does It Take Long To Reduce The Charge Of A Capacitor By 10 μc?

It does not take long to reduce the charge of a capacitor by 10 μc. It takes a mere 7 seconds to do reduce the charge. 7 seconds pass in a moment without even realizing. On the other hand, it is noted that charging up a capacitor with the same amount takes longer. It takes about 15 seconds to charge up in comparison to the 7 seconds. It is mathematically proven and there is no room for error.

Capacitors are nonlethal and cannot cause any harm to human beings in the first place. But the voltage stored and the current discharged from it can cause harm. People should avoid touching capacitors especially when they are charged as it may discharge current. Even if the capacitors are not energized, it is advised to not touch them as there still might be current after turning off the electricity.

The structure of a capacitor is generally small but there are exceptions regarding this matter. Its structure differs when it is used in larger objects. The small capacitor will not be enough for large electrical devices. Not only structure, but its theory of operation also differs from one another. Hydraulic analogy, parallel plate capacitor, interleaved capacitor are a few of the examples.

With each theory, the mathematical formula, to know the charge, changes. The more complicated the theory, the more difficult it becomes to know the charge. Capacitors can be used in both AC circuits and DC circuits. Capacitors can also be joined in series.

## Conclusion

Everything in science has a rule to it. To use any particular creation of science it is suggested to stick by the rules attached to it. The capacitors are no different. It should only be handled by experts and should be prevented from coming into the hands of children. Capacitors are used in a lot of electrical devices but are not visible because it is generally located inside the devices. If any device is opened up, the capacitors can be found.

To prevent any kind of mishaps, it should be mathematically calculated to know the exact time required to reduce or charge up the capacitor. Everything has a good and bad side, just like the old saying ‘science is a good servant but a bad master’.
