Electrolytic capacitors use an aluminum or tantalum plate with an oxide dielectric layer. The second electrode is a liquid electrolyte, connected to the circuit by another foil plate. Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures, which increases equivalent series resistance. While widely used for power-supply conditioning, poor high-frequency characteristics make them unsuitable for many applications. Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes). They can be restored before use (and damage) by gradually applying the operating voltage, often done on antique vacuum tube equipment over a period of 30 minutes by using a variable transformer to supply AC power. Unfortunately, the use of this technique may be less satisfactory for some solid state equipment, which may be damaged by operation below its normal power range, requiring that the power supply first be isolated from the consuming circuits. Such remedies may not be applicable to modern high-frequency power supplies as these produce full output voltage even with reduced input.
What is one type of metal which the conducting plates in electrolytic capacitors are commonly made of?
****
The answer: aluminum

Madonna was born to Catholic parents Silvio Anthony "Tony" Ciccone (b. 1931) and Madonna Louise Fortin (c. 1933 December 1, 1963) in Bay City, Michigan, on August 16, 1958. Her father's parents were immigrants from Pacentro, Italy, while her mother was of French-Canadian ancestry. Tony worked as an engineer designer for Chrysler and General Motors. Since Madonna had the same name as her mother, family members called her "Little Nonni". She has two elder brothers, Anthony (born 1956) and Martin (born 1957), and three younger siblings, Paula (born 1959), Christopher (born 1960), and Melanie (born 1962).
What was Tony's occupation?
****
The answer: engineer designer

Christianity came to Tuvalu in 1861 when Elekana, a deacon of a Congregational church in Manihiki, Cook Islands became caught in a storm and drifted for 8 weeks before landing at Nukulaelae on 10 May 1861. Elekana began proselytising Christianity. He was trained at Malua Theological College, a London Missionary Society (LMS) school in Samoa, before beginning his work in establishing the Church of Tuvalu. In 1865 the Rev. A. W. Murray of the LMS a Protestant congregationalist missionary society arrived as the first European missionary where he too proselytised among the inhabitants of Tuvalu. By 1878 Protestantism was well established with preachers on each island. In the later 19th and early 20th centuries the ministers of what became the Church of Tuvalu (Te Ekalesia Kelisiano Tuvalu) were predominantly Samoans, who influenced the development of the Tuvaluan language and the music of Tuvalu.
Of what nationality were most of the ministers of the Church of Tuvalu?
****
The answer: Samoans

Despite the fact that humans have occupied the territory of Portugal for thousands of years, something still remains of the original vegetation. In Geres both deciduous and coniferous forests can be found, an extremely rare worldwide mature mediterranean forest remain in some parts of the Arrabida mountain and a subtropical laurissilva forest, dating back to the Tertiary period, covers its largest continuous area in the world in the Madeira main island. Due to the human population decrease and rural exodus, Pyrenean oak and other local native trees are colonizing many abandoned areas. Boar, Iberian red deer, roe deer, Iberian wild goat, for example, are reported to be expanding greatly, during the last decades. Boars were found recently roaming at night inside large urban areas, like in Setubal. Protected areas of Portugal include one national park (Portuguese: Parque Nacional), 12 natural parks (Portuguese: Parque Natural), nine natural reserves (Portuguese: Reserva Natural), five natural monuments (Portuguese: Monumento Natural), and seven protected landscapes (Portuguese: Paisagem Protegida), which include the Parque Nacional da Peneda-Geres, the Parque Natural da Serra da Estrela and the Paul d'Arzila.
To what period does the laurissilva forest date back to?
****
The answer:
the Tertiary period
