Phase-shifting circuits
Phase shifting circuits are used to correct an undesirable phase-shift (or produce a desired one.) In the Impedance and Admittance tutorial, we discussed the concept of impedance as expressed in rectangular form and learned that when the reactance is capacitive in nature, current leads the applied voltage.
