    Why is there a small neutral current in a balanced three-phase system?

    oh yes its a 3 -phase system with an 80 ohm res,40F capacitor and 4H inductor, star source delta load(Vp =65v,VL =110v,Ip =1.3,IL =2.3,wattmeter =138w) star source star(Vp =62.5, VL =109, Ip= 0.5, IN= 0, wattmeter 1=60w and wattmeter 2=11w).these are the details .thank you.it is a course work

    Why is there a small neutral current in a balanced three-phase system?

    hi guys i have juss did my connections on a balanced system and the Nuetral current suppose to be zero.the question is to explain why I recorded a small value of neutral current. thank hope to hear from you soon.

    How does a Wein bridge oscillator work?

    hi guys I am new in this forum hope I am not lost.I am desperately asking for your help on how a wein bridge oscillator works by referring to phase shift and attenuation of the wein bridge networkthe phase shift and amplification provided by the amplifier and the type of feedback produced.thank you
