Weba) Find the impedance of winding 1 and winding 2 without the capacitor. Find both in rectangular form. b) If the capacitor were disconnected from winding 2 and placed in series with winding 1 instead, find the new phase angle difference and the new current magnitudes. Did anything improve? WebThe voltage across the capacitor has a phase angle of -10.675°, exactly 90° less than the phase angle of the circuit current. This tells us that the capacitor’s voltage and current are still 90° out of phase with each other. Calculations Using SPICE. Let’s check our calculations with SPICE: Spice circuit: R-C. WebA 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: inbouwbad whirlpool
