0:00 Overview • 1:07 Apparent power • 2:38 Star connection • 4:13 Delta connection • 5:28 Formula for apparent power • 6:19 Task example • 8:25 Quiz • This video is about the basics of electrical engineering, more precisely, about three-phase current, and even more precisely, about the comparison of power with delta connection and star connection. • Three-phase current: Why does the motor draw more power from the mains if it is internally connected in delta? What is the difference between phase voltage and phase-to-phase voltage? How do you calculate the apparent power of a delta connection and that of a star connection? Why are the powers different, even if the phase voltages are the same? It's explained simply here, with an example calculation. At the end there is a mnemonic and a quiz where you can test your newly acquired knowledge.
