  • good job 

  • Thank you so much i would fail my test without this! THANKU

  • Current is through, not across.

  • ohm my god, I'm shocked.

    Is resistance futile?

    Now do power factor correction for a 440v, 3ph motor at 80% efficiency and 80% PF, how much capacitance is needed to make the motor operate at 95% PF?

    Easier way to solve your problem: 1 over 1/2+1/3+1/4 = total R.

    Resistance will always be lower than the lowest value in parallel (less than 2 ohms in your circuit.

    1 divided by 0.5+0.33+0.25 = 0.923 ohms. E=I*R

    12v=I*0.923

    I=12.999

    Your circuit will have 12.999 amps total.

  • @CalicoatMaker you are incorrect did you think someone would not notice?

  • nice man :D

  • Thank you very much...
