hi thanks for replying the energy ic is an ade7752B analog device ic. It measures 3 phase power if you feed it voltage and current inputs from each phase. Yes, i know you need a current transformer, I just didnt mention it. I wanted to be sure about the current on the secondary side and so...

Hi Im building an energy meter and I have a doubt about the voltage channel I am using to measure voltage. Basically there is a transformer that is connected between line and neutral and on the secondary side, there is voltage dividing resistor circuit to step down the voltage to the levels...

Hello, I noticed that with my radio sometimes when I am getting static if I bring my hand close to the antenna, the radio suddenly becomes clear and I can hear the station very clearly.I can either touch the antenna with some metal, or more dramatically, I just bring my hand close to the...

Hey thanks but can't i do it the way i did it?

Homework Statement two electric field vectors- E1= E0 cos (kz-wt) i(carat) and E2=E0 cos (kz+wt) i(carat) . what is the magnetic field vector corresponding to the the superposition of these 2 waves? Homework Equations The Attempt at a Solution E=E1 + E2 = E0 [2cos{(...

hey thanks! a lot. how did you get the integral signs? (the big s) and the proper format?

[SOLVED] integral problem Homework Statement hi. my problems an integral which i can't solve. the integral is this- integral of [1-(e^(t/a))]^2 dt a is a constant. it came when i tried to find the total power through a LR circuit Homework Equations The Attempt at a...

hi in what direction does the electrostatic force act when we insert a dielectric within a capacitor? and when we remove the dielectric? supposedly they act in opposite directions in each case, and either push or pull the dielectric out or into the capacitor. i m not able to understand how the...
