Input: Read this: The current–voltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor.
Question: What is a solution to preventing an LED failure?

Output: use constant-current power supplies


QUES: Various industrial businesses are located in Hannover. The Volkswagen Commercial Vehicles Transporter (VWN) factory at Hannover-Stöcken is the biggest employer in the region and operates a huge plant at the northern edge of town adjoining the Mittellandkanal and Motorway A2. Jointly with a factory of German tire and automobile parts manufacturer Continental AG, they have a coal-burning power plant. Continental AG, founded in Hanover in 1871, is one of the city's major companies, as is Sennheiser. Since 2008 a take-over is in progress: the Schaeffler Group from Herzogenaurach (Bavaria) holds the majority of the stock but were required due to the financial crisis to deposit the options as securities at banks. TUI AG has its HQ in Hanover. Hanover is home to many insurance companies, many of which operate only in Germany. One major global reinsurance company is Hannover Re, whose headquarters are east of the city centre.

What types of company does Hanover have that operate around the world?

Hydrogen is a chemical element with chemical symbol H and atomic number 1. With an atomic weight of 7000100794000000000♠1.00794 u, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.[note 1] Non-remnant stars are mainly composed of hydrogen in its plasma state. The most common isotope of hydrogen, termed protium (name rarely used, symbol 1H), has one proton and no neutrons.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is hydrogens chemical symbol?
Ah, so.. H


Question: Hiberni (Ireland), Pictish (northern Britain) and Britons (southern Britain) tribes, all speaking Insular Celtic, inhabited the islands at the beginning of the 1st millennium AD. Much of Brittonic-controlled Britain was conquered by the Roman Empire from AD 43. The first Anglo-Saxons arrived as Roman power waned in the 5th century and eventually dominated the bulk of what is now England. Viking invasions began in the 9th century, followed by more permanent settlements and political change—particularly in England. The subsequent Norman conquest of England in 1066 and the later Angevin partial conquest of Ireland from 1169 led to the imposition of a new Norman ruling elite across much of Britain and parts of Ireland. By the Late Middle Ages, Great Britain was separated into the Kingdoms of England and Scotland, while control in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland, soon restricted only to The Pale. The 1603 Union of the Crowns, Acts of Union 1707 and Acts of Union 1800 attempted to consolidate Britain and Ireland into a single political unit, the United Kingdom of Great Britain and Ireland, with the Isle of Man and the Channel Islands remaining as Crown Dependencies. The expansion of the British Empire and migrations following the Irish Famine and Highland Clearances resulted in the distribution of the islands' population and culture throughout the world and a rapid de-population of Ireland in the second half of the 19th century. Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with six counties remaining in the UK as Northern Ireland.
Try to answer this question if possible: The Hiberni tribes of northern Britain speak which language?
Answer: unanswerable


QUES: The English concentrated on the spirit of the events of Christ's life, not the literality of events. They neither expected nor sought the appearance of the stigmata or any other physical manifestation. They wanted to create in themselves that environment that allowed Jesus to fulfill His divine mission, insofar as they were able. At the center of this environment was love: the love that Christ showed for humanity in becoming human. Christ's love reveals the mercy of God and His care for His creation. English Dominican mystics sought through this love to become images of God. Love led to spiritual growth that, in turn, reflected an increase in love for God and humanity. This increase in universal love allowed men's wills to conform to God's will, just as Christ's will submitted to the Father's will.
What did the English Dominican Order not want to create in themselves?
