question:
In solid-state physics, a dimensionally-equivalent "sheet" version of this quantity is often reported as its value "per square". Its quantum is equal to h over e squared, and the Drude model gives this extensive quantity as inversely proportional to the product of carrier number density and mobility. A complex version of this quantity includes a term equal to frequency times inductance. The power dissipated in a circuit equals (*) current squared times this value. Voltmeters work by applying a very large value for this quantity in parallel. Devices that provide this quantity are marked with a series of colored bands and symbolized with a zig-zag line. For 10 points, name this quantity set equal to voltage over current in a law named for Ohm, who also names its SI unit.
answer:
Science

question:
This work premiered as part of a charity concert series and was troubled by last-minute rearrangements and other production difficulties. After various demands from Jonathan Swift, the dean of St. Patricks Cathedral, the work was finally allowed to premiere on April 13, 1741 in Dublin.

The finale chorus of the work is borrowed from Revelation, while a good deal of the remaining libretto is taken from the Old Testament. FTP, name this oratorio by George Frederic Handel, most famous for the chorus Hallelujah.
answer:
Fine Arts

question:
Cell bodies in which this substance has not yet been synthesized are called etioplasts. The synthesis of this substance is stimulated by cytokinin and can be inhibited by iron deficiency. Its catabolism is accompanied by an increase in pheophytin a and results in its conversion into a set of tetrapyrrole compounds. This porphyrin contains a central (*) magnesium ion, and its "E" type is found only in two species of golden algae. It is located in structures that are arranged in grana, thylakoids, where it is arranged with protein complexes called photosystems. For 10 points, name this green plant pigment that helps capture light energy.
