Admittance represents the ease with which current flows through a circuit. It comprises conductance (real part) and susceptance (imaginary part). Admittance, like impedance, is a valuable tool in AC circuit analysis, enabling engineers to understand and manipulate electrical circuits operating under sinusoidal conditions.

Learn MoreIf one were tasked with determining the total effect of several parallel-connected, pure reactances, one could convert each reactance (X) to a susceptance (B), then add susceptances rather than diminish reactances: X parallel = 1/(1/X 1 + 1/X 2 + . . . 1/X n). Like conductances (G), susceptances (B) add in parallel and diminish in series.
Learn MoreI e Fig 4.4 The impedance of an a.c. circuit is a complex number, but is not a phasor. Since the value is complex, it has a real part (the resistance) and an imaginary part (the reactance). That is it can be expressed in rectangular complex form as Z = R ± jXohm Similarly, the admittance of an a.c. circuit is a complex number which not

Learn MoreUnlike a resistor, the voltage and current will not be in phase for an ideal capacitor or for an ideal inductor. For the capacitor, the current leads the voltage across the capacitor by 90 degrees. Recall that the voltage across a capacitor cannot change instantaneously, (i = C, dv/dt). For an inductor, the voltage leads the current by 90 ...

Learn MoreA closer look at the phase angle mapping, and it looks like the admittance phase angle is just the reflection of the impedance phase angle about the real/X axis. For example, an impedance phase angle of 45 degrees is equal to an admittance phase angle of -45 degrees. And this makes sense if I had used some identities above:
Learn MoreThen identify the first element connected to the load (a capacitor in shunt) and convert to admittance. This gives us point A''. Determine the arc portion where the next point will appear after the connection of the capacitor C. As we don''t know the value of C, we don''t know where to stop. We do, however, know the direction.

Learn MoreA capacitor will charge up (like a quick-acting battery) when voltage is applied to it. When the polarity change (as it does in an AC circuit), the capacitor will start to discharge. When the capacitor discharges, it is opposing the change in voltage. Once the capacitor is fully discharged, it starts to charge up again in a reversed configuration.
