- An anode usually is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, which is usually an electrode of the device through which conventional current leaves the device. A common mnemonic is ACID, for anode current into device. The direction of conventional current (the flow of positive charges) in a circuit is opposite to the direction of electron flow, so (negatively charged) electrons flow from the anode of a galvanic cell, into an outside or external circuit connected to the cell. For example, the end of a household battery marked with a + is the cathode (while discharging).
- Blaine — Thumbnail History (historylink.org)
Blaine (Whatcom County) is located in extreme Northwestern Washington; the northern edge of its city limit is the Canadian border. The area was originally inhabited by a band of Native Americans known as the Semiahmoo. Caucasian settlers first arrived in 1858 during the Fraser River Gold Rush, when not one, but two communities named Semiahmoo were briefly established. Permanent settlement came in 1870, and eventually the two Semiahmoos became one Blaine. In the early twentieth century, Blaine was known for its canneries, including one of the largest in the country, the Alaska Packers Association, located on Semiahmoo Spit. Today (2009) the four-star Semiahmoo Resort sits on the spit, and on the northern outskirts of Blaine the Peace Arch and Peace Arch Park provide a unique and attractive gateway for those entering or leaving the United States. In 2008, the U.S. Census estimated Blaine’s population at 4,975.
