if resistence in series with the diode and voltegesupply isknown then how to calculate forward&reverse current


give me the procedure.

current = voltage / resistance. No "reverse" current through a diode.

The Diodes


The Diodes


$93.99


High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

In this book, I have optimized the growth of n and pGaN films, and high quality InGaN/GaN multiple quantum wells (MQWs) on sapphire (0001) substrate by a low pressure metalorganic chemical vapour deposition and have fabricated high brightness InGaN/GaN MQW lightemitting diodes (LEDs) under optimum conditions. To improve quantum efficiency which is generally poor in the conventional rectangularshaped QWs due to spatial indirect recombination induced by internal piezoelectric field, we proposed a possibility of quantum dot (QD) engineering with triangularshaped band structure in the InGaN/GaN QWs. The structural and optical properties of the InGaN/GaN MQWs with different threading dislocation densities were also investigated. The effects of Sidoped nGaN and Mgdoped pGaN layers on the electrical and optical properties of the InGaN/GaN MQW LEDs were investigated and optimized under various growth parameters.

Organic lightemitting diode (OLED) technology is used in a variety of display applications, ranging from cell phones and MP3 to prototype TVs, and holds great promise for the production of highly efficient largearea light sources and flat panel displays. It has the potential to become a multibilliondollar industry within a few years. The biggest technical challenge for OLEDs is the limited lifetime associated with elevated temperatures and exposure to moisture. The guaranteed hours of operation (15,000 hr) is currently inadequate for most TVs and replacement of LCDs with the 60,000 hr halflife. This book, therefore, investigated the thermalactivated and moistureinduced degradation pathways of small molecule based prototype OLEDs as well as interfacial electronic properties at the nanoscale level through realtime visualization. The results should help shed some lights on improving luminescence efficiency and lifetime of OLEDs, and should be especially useful to professionals in research and development of not only OLED technology but other organic electronics, or anyone else who may be interested in plastic electronics.

Revised and fully up-dated, the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. Elementary properties such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III-V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises, solutions, and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering, applied physics, and materials science.

3 Diodes in Series Regulator

Can two power supply connected in series?


I intend to charge a 24vdc battery,I have two similar power supplys which output is 12vdc each, may I know the connection to charge the battery ,if don't mind please draw the diagram
Is a blocking diode necessary??
thanks!!

Its hard to draw the circuit here. But, the connection is simple. Connect the two batteries in series ie positive of one to the negative of the other to form 24Vdc. Then connect the positive of the 24vdc batteries together and the negatives together.
Try using the diagram i've attempted to draw below. 'DD' represents the blocking diode with its polarity indicated.
Be careful to place the diode correctly or the 24V battery will charge the two 12v batteries
