It really does depend upon what you mean by 'shift'.
For purely-resistive circuits, the load current is in phase with the supply voltage. For reactive circuits, the load current will lead or lag the supply voltage; for capacitive-resistive circuits, the load current leads, whereas for inductive-resistive circuit, the load current lags.
You can change the angle by which the current leads or lags (the 'phase angle') by changing the amount of resistance or reactance.

An induction motor has an AC power source applied to the stator and an AC source applied to the rotor, through slip rings. The rotor spins a sub synchronous speed, which creates the phase shift between rotor AC and stator AC. This phase shift (known as slip) is what creates the torque.
A capacitor introduces a phase shift in an alternating current (AC) circuit because it does not allow current to change instantaneously. When an AC voltage is applied, the capacitor charges and discharges, causing the current to lead the voltage by 90 degrees in a purely capacitive circuit. This phase difference results from the time it takes for the capacitor to build up and release charge, which affects the relationship between voltage and current in the circuit. Thus, the presence of a capacitor alters the phase relationship between these two electrical quantities.
Capacitive phase shift refers to the delay in the voltage across a capacitor compared to the current flowing through it in an AC circuit. In a capacitive circuit, the current leads the voltage by a phase angle of 90 degrees, meaning that the peak current occurs before the peak voltage. This phase difference results from the capacitor's ability to store and release energy, affecting the overall impedance and behavior of the circuit. Understanding capacitive phase shift is essential for analyzing and designing circuits involving capacitors, especially in applications like filters and oscillators.
There is no such thing as phase in DC as phase requires AC. To have two or more things out of phase requires them to be changing. Only AC does that. DC is steady state.

Power Factor measures the phase shift between current and voltage waveform. Since DC has no frequency there can be no phase shift.
An induction motor has an AC power source applied to the stator and an AC source applied to the rotor, through slip rings. The rotor spins a sub synchronous speed, which creates the phase shift between rotor AC and stator AC. This phase shift (known as slip) is what creates the torque.
AC - DC ... analog - digital ... frequency - phase shift ... AM - FM
The phase-shift oscillator gets its name from the phase-shift network used in its design, which introduces a phase shift in the feedback path of the circuit. This phase shift is necessary for maintaining oscillations in the circuit.
phase shift in integrator is 180 degrees and phase shift in differentiator is 0 degrees
Three phase is ac
Due to its negative gain and 180' phase shift between base and collector
The phase shift angle of an RLC circuit is constant for a constant frequency, but changes with different frequencies.The phase angle of the AC in the RLC circuit is however continuously changing. Otherwise it wouldn't be AC.
There is no phase shift.
The phase constant formula used to calculate the phase shift in a wave is 2/ d, where is the phase shift, is the wavelength of the wave, and d is the distance traveled by the wave.
