If you are starting to learn more about electronics, you will likely learn about active and passive components. There are ways to test them to see if there is a problem with the flow of electricity. Whether you have circuit boards, or you have these larger electronic components that allow things to work, it is the flow of electricity through them that allows them to work. There are times when the flow of electricity is not needed. This is going to be prevented by what are called passive components. On the other hand, when the flow of electricity is necessary, active components are going to allow this to happen. If you need to test any of the active components that you have, this is an overview of how you can do this.

Some Of The More Common Active Components

Active components such as a diode, transistor, or even an integrated circuit, are going to have problems from time to time. There could be a short in the circuit, usually the result of some type of physical problem, and if that occurs they will need to be replaced. For example, you may have light emitting diodes which are active components. When they failed to light up, there is a problem with the circuitry. However, that does not necessarily mean that the active component itself has something wrong. There could be a short in the circuitry leading up to that diode.

How Can You Test The Electronic Equipment That You Have?

There is a device called a multi meter, or an AVO Meter, that can be used to determine if there are problems with your electronic circuitry. In the case of active components that may not be working, you can actually test the flow of the electricity that should be going through it. There are going to be what are called test probes, needles that are at the end of what are called test leads. These are going to plug into the multi meter, and depending upon the setting of this device, you can determine if there is proper flow or if there is none at all.

Different Types Of Multimeters Of People Use

There are a couple different types that you will see for sale online. One of the first that was made was called an analog multi meter. This is going to have a bar that will swing up and down in an arc. The position of that bar will correspond with numerical data. When you are using a digital one, you will see these numeric readings on a digital display. They are both testing for the same things, but some people prefer to see the numbers, opposed to trying to see where the bar is positioned on the analog display.

What If You Have Active Components That Are Not Working?

If you do have a few active components that need to be replaced, you can remove them using a soldering iron. You will simply heated up, and this will allow you to melt the solder, a type of metal that is very easy to change into a semi liquid form. This is used on most devices that are made today. It is a bright silver material, something that is made from both tin and copper. There are also those that are completely leadfree, but regardless of what you are using, the soldering iron will allow you to detach the broken active component and replace it with the new one.

Now that you know how to test active components with the multi meter, you might want to start looking at what is wrong with your electronic device. You need to make sure that you are getting proper readings. You will need to learn how to put the settings properly on these devices. Once you have determined that there is a problem, you can use a soldering iron to remove the active components and replace it with one that is working. Over time, you could become quite adept at doing so, allowing you to potentially transition from doing this as a hobby to providing this is a service. For more details visit http://www.directics.com
