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.
Suppose you suspected a failed-open diode in this power supply circuit. Describe how you could detect its presence without using an oscilloscope: Low-voltage AC power supply 6 6 12--Rectifier assembly Filter capacitor Incidentally, the âlow voltage AC power supplyâ is nothing more than a step-down transformer with a center-tapped secondary winding. ï¬le 00794 Question 16 A student learns that a rectiï¬er circuit is often followed by a low-pass ï¬lter circuit in an AC-DC power supply to reduce ârippleâ voltage on the output. to build this power supply circuit complete with a low-pass ï¬lter at the output: While this design will work, there are better ï¬lter conï¬gurations for this application. limitations of the circuit shown, and explain how some of the other ï¬lters would do a better job.
