Alternating Current
Alternating current signal
AC means Alternating Current and DC means Direct Current. AC and DC are also used when referring to voltages and electrical signals which are not currents! For example: a 12V AC power supply has an alternating voltage (which will make an alternating current flow).

Full wave bridge rectifier
This document describes the operation of a full wave bridge rectifier circuit. It explains that two diodes conduct during the positive half cycle and the other two conduct during the negative half cycle, allowing current to flow through the load in only one direction. This produces a full wave rectified output with both half cycles used. The input AC waveform is shown along with the rectified DC output waveform. Advantages of the bridge rectifier are listed as not requiring a center-tapped transformer and producing twice the output of a center-tap circuit for the same secondary voltage. Disadvantages include requiring four diodes and having double the voltage drop across the diodes compared to a center-tap rectifier.

The document discusses the results of a study on the impact of climate change on coffee production. Researchers found that suitable land for coffee production could decline by up to 50% by 2050 due to rising temperatures and changing rain patterns associated with climate change. The study concludes that climate change poses a major threat to the coffee industry worldwide as suitable land decreases substantially in the coming decades if greenhouse gas emissions are not reduced.
