A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store electrical energy temporarily in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors (plates) separated by a dielectric (i.e. an insulator that can store energy by becoming polarized). The conductors can be thin films, foils or sintered beads of metal or conductive electrolyte, etc. The nonconducting dielectric acts to increase the capacitor's charge capacity. Materials commonly used as dielectrics include glass, ceramic, plastic film, air, vacuum, paper, mica, and oxide layers. Capacitors are widely used as parts of electrical circuits in many common electrical devices. Unlike a resistor, an ideal capacitor does not dissipate energy. Instead, a capacitor stores energy in the form of an electrostatic field between its plates.
How many electrical conductors, or plates, do all capacitors contain at a minimum?
two electrical conductors

Contrarily, having so firmly entrenched themselves into Greek affairs, the Romans now completely ignored the rapidly disintegrating Seleucid empire (perhaps because it posed no threat); and left the Ptolemaic kingdom to decline quietly, while acting as a protector of sorts, in as much as to stop other powers taking Egypt over (including the famous line-in-the-sand incident when the Seleucid Antiochus IV Epiphanes tried to invade Egypt). Eventually, instability in the near east resulting from the power vacuum left by the collapse of the Seleucid empire caused the Roman proconsul Pompey the Great to abolish the Seleucid rump state, absorbing much of Syria into the Roman republic. Famously, the end of Ptolemaic Egypt came as the final act in the republican civil war between the Roman triumvirs Mark Anthony and Augustus Caesar. After the defeat of Anthony and his lover, the last Ptolemaic monarch, Cleopatra VII at the Battle of Actium, Augustus invaded Egypt and took it as his own personal fiefdom. He thereby completed both the destruction of the Hellenistic kingdoms and the Roman republic, and ended (in hindsight) the Hellenistic era.
Which Roman proconsul ablished the Seleucid rump state?
Pompey the Great

The southern Essonne department specialises in science and technology, and the south-eastern Val-de-Marne, with its wholesale Rungis food market, specialises in food processing and beverages. The Paris region's manufacturing decline is quickly being replaced by eco-industries: these employ about 100,000 workers. In 2011, while only 56,927 construction workers worked in Paris itself, its metropolitan area employed 246,639, in an activity centred largely around the Seine-Saint-Denis (41,378) and Hauts-de-Seine (37,303) departments and the new business-park centres appearing there.
