Just as it sounds, rectification is the process of converting alternating current to direct current. To carry out this process, we are going to make use of a bridge rectifier. A bridge rectifier consist of four diodes some bridge rectifiers have now been made into a single chip. Diodes are semiconductor materials that allows currently to flow only in One Direction (which is usually in the forward dirction), thereby removing the negative cycle of the alternating current, thus producing a fluctuating DC. The small silver band on the diode represent the cathode. And the large black band represent the anode.

Ahh I have so many things I wanted to fix. I just hot air reworked an onboard lan chip. BUt i can't figure out what's wrong as there's no led light for gigabit connection. That's my dilemma for now haha.

As you can see, aspheric lenses offer many aesthetic and vision-correcting benefits for their wearers. But just like any prescription, these types of glasses or contact lenses should be thoroughly discussed with your eye doctor to make the best decision for you. Even if you’re considering non-prescription readers with aspheric lenses, it's worth it to mention the change to your doctor.

Not only are ‘coke bottle lenses’ a thing of the past, but aspheric lenses also offer a better degree of vision correction. When wearing traditional lenses, you may notice some visual distortion when you look anywhere other than the direct center of the lens. Aspheric lenses, on the other hand, promote a wider field of vision with better peripheral vision and more consistent overall image magnification, allowing for clearer and more accurate vision. This is the same reason many photographers prefer aspheric camera lenses - a wider field of vision means more of the beautiful world is accurately captured in a single glance.

Disadvantagesofaspheric lenses

While traditional lenses have gone far to help the millions of people who suffer from farsightedness or nearsightedness, they add a marked spherical, convex curvature to the shape of the lens. This can distort the appearance of the eyes and facial areas. Traditional convex lenses can create a magnifying, bug-eyed effect on farsighted prescriptions or a minimizing, beady-eyed effect on nearsighted prescriptions. This noticeable curvature of the lens distorts the appearance of the wearer and the glasses alike, detracting from overall perceived attractiveness while also dealing an unnecessary blow to self-confidence.

The technology behind aspheric glasses and contact lenses is directly related to advances made in camera lens technology. Just like the human eye, some camera lenses are shaped in such a way that visual aberrations and distortion can occur in the images they capture. The shape of the eye can also contribute to distorted vision. That’s why lenses are specially designed to balance and correct for the unique shape of a person’s eye—and why the technology has had to come a rather long way.

Finally, as mentioned in the beginning of this article, aspheric lenses are also an option for some contact lens wearers. However, the performance of aspheric contact lenses, when compared with that of aspheric glasses, may leave something to be desired. Many find that regular, spherical contact lenses work just as well, if not better than the newer aspherical contact lenses do. With two primary options of aspheric contact lens prescriptions being bifocal and multifocal, visual aberrations can be corrected in the wearer. However, visual contrast may reduce slightly, while glare caused by driving at night may increase - particularly for those who wear multifocal aspheric contacts. For these reasons, aspheric contact lenses may not be for everyone.

Nonaspheric lenses advantages disadvantages

The major disadvantage of aspheric lenses is their price. These advanced vision correcting lenses cost more to manufacture than traditional lenses do, involving more steps, more precision, and more labor. If you have an extremely mild need for vision correction, then aspheric lenses may not be the most logical choice for you.

With the advancement of aspheric lens technology, we now have more glasses frame styles available to more people than ever, with significantly less bulging of the lens and a lightweight feel for comfortable wear. These advanced lenses are cut to a slimmer profile, with much flatter curves that are strategically shaped depending upon the wearer’s prescription. This slim profile means that the glasses frames can sit closer to the face for a much more natural, streamlined look. This is a big advancement for folks with especially high prescriptions. If you’re in the market for aspheric lenses, limited frame materials, shapes, and sizes are no longer an issue, either.

When the positive cycle of the AC comes into the system, D1 and D2 are forward biased and D3 and D4 are reversed biased therefore current will flow only through D1 and D2. While in the negative half cycle D3 and D4 are forward biased while D1 and D2 are reversed biased, hence current flows through D3 and D4.

Dude totally love your post. Im new to this electronic field. This article is so useful for all electronic newbie out there. Cause i believe every tinkerer must start with building your own power supply. Its the most basic. Great jib with your explanations. I do hope more such post from you.

for those of us who have a 9-0-9 trans former, Peak voltage =9×√2 =9×1.4142 =12.7278v Voltage drop across diodes =1.4 as we established above. V=12.7278 - 1.4 =11.3278v 11.3278 - 7 Hence V=4.3278 From C=I×(T/V) C=500mA×(10ms/4.3278) =1154.7uf But we don't have this kind of value for a capacitor so we approximate to 1000uf. Hence C =1000uf.

now the voltage from the main, that is from your sockets at home is usually very high. Here in Nigeria it ranges from 220-240v and on some occasions 250v. In other to step down this voltage we are going to use a step down transformer (preferably 12v), by simply connecting the primary wire of the transformer to the main and the secondary to your bread board.

Another factor to consider is that, due to their flatter profile and closer proximity to the face, aspheric lenses may produce noticeable reflections for some wearers. Anti-reflective coating is recommended for all aspheric lens wearers to eliminate any potential for visual distraction that reflections can cause.

Hello Steemians I did a post last week on how to trouble shoot your car battery. you can look it up here. Today am going to be posting on how to build your own 5volt power supply. Maybe you might have had a damaged charger and then you wished you could just build a temporary one before you are able to get a new one or maybe you are like me who loves electronics so much and then you begin to get worried that you are spending too much on batteries, don't worry because this post is going to guild you on how to build a 5volt power supply for your projects. The components needed to carry out this project are going to be as follows;

In general, many people with moderate to high need of vision correction for nearsightedness or farsightedness can benefit from the advances of aspheric lenses, particularly if worn in prescription glasses. Those with lower prescriptions will not see noticeable improvements to make the cost of aspheric lenses worthwhile. While some may want to try aspheric contact lenses, particularly those with bifocal rather than multifocal prescriptions, the benefits are mixed and should be discussed with your eye doctor. Those with astigmatism may not benefit as high as others and may be better off discussing toric lens options. Finally, aspheric lenses are a good option for many who use non-prescription reading glasses, too! If your readers are at a high reading power of +4.00 or higher, you may want to explore aspheric options.
