phase

i salute the entire community! below is a phasor diagram ; a point got stuck in my head when the signal and systems were working where I indicated with the red arrows, these arrows are always 0 -> 90 -> 180 -> 270 -> 360 is this happening because he is following in his form? or do these...

i salute the whole community! in signals and systems, I'm learning things about the phasor drawing of the given sinusoidal signs. when researching on the Internet, the negative phases are counterclockwise i came across articles that the positive phases are clockwise. but when you do it with...

Hi, I have to on-off switch a AC load, which delta connected 3 phase AC source. Consider the load that will be switched on-off is Z1. To achieve on-off switch, I think use zero cross triac opto driver and triac for both Phase-R and Phase-Y. But I am confused. When Phase-R reaches zero point...

Say there are 3 buses of: Bus 1: Slack bus with a voltage source of E=1.0 and phase of 0° Bus 2: a generator and a load. Bus 3: a load. The line impedance are given below: z12 = 0.05 + j0.1 z13 = 0.02 + j0.05 z23 = j0.05 z11 = -j100 z22 = infinity z33 = -j40 The generators and loads are given...

Hello, everyone! I have a problem with approaching a university project, which aim is to detect the phase drifts (difference, deviation) between a mains supply voltage and either an internal reference and externally input reference signal. The system should be micro-controller based (MSP430)...

Hello, I am new to hardware design. I am designing measurement circuit for Impedance Spectroscopy of electrochemistry cell. I need to measure the current coming from electrodes which have range from few milliamperes to few nanoamperes. as literature suggested, the equivalent circuit for...
