Unformatted text preview: Experiment 46 Three-Phase Watts, Vote, and Uelt—Amperes OBJECTIVE ' To determine the apparent. active and reactive power in dime-phase circuits. - To eeiculete the power factor in three~phese circuits. DISCUSSION In Experiment 45 ym calculated active power in threepheee circuits. You 1.Irlll rie'rur team that reactive power [eithercenecitive er it'iducfiira} can man be awaited in a similar manner. it titeretereieliews thet apparent power-end pewerfectercen else be calculated for balanced Elma-phase circuits. .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
