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. WebAC Voltage in a Capacitor When a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a 90º phase angle. The capacitor is affecting the current, having the ability to stop it altogether when fully charged.
