Best Answer: B) Evolutionary relationships-This is because the classification system works by grouping together related species that have evolved from common ancestry No others are plausible.
Short for uninterruptible power supply, a power supply that includes a battery to maintain power in the event of a power outage. Typically, a UPS keeps a computer running for several minutes after a power outage, enabling you to save data that is in RAM and shut down the computer gracefully.
An essential part of an AC-DC power supply circuit is the ï¬lter, used to separate the residual AC (called the ârippleâ voltage) from the DC voltage prior to output. Here are two simple AC-DC power supply circuits, one without a ï¬lter and one with: Filter Plug Vunfiltered Vfiltered Plug Draw the respective output voltage waveforms of these two power supply circuits (V unfiltered versus V filtered).
