The circuit on the left shows a single resistor-capacitor network whose output voltage "leads" the input voltage by some angle less than 90 o a pure or ideal single-pole RC network. it would produce a maximum phase shift of exactly 90 o, and because 180 o of phase shift is required for oscillation, at least two single-poles networks must be used within an RC oscillator design.
You may become confused when you try to use the dual trace feature of the scope, for example, to demonstrate the 90° phase shift of a capacitor, unless you understand how the leads are grounded.. One side of both scope leads is grounded, and one side of the signal generator is grounded. This prevents you from hooking up the naive circuit below to show the 90° phase shift.
One RC takes an infinite amount of time to produce a 90 degrees phase shift so for 180 degrees, three 60 degrees of phase shifts are used. A
In this article, "phase shift" will refer to the difference in phase between the output and the input. It''s said that a capacitor causes a 90° lag of voltage behind current, while an inductor causes a 90° lag of current behind voltage. In phasor form, this is represented by the + j or -j in the inductive and capacitive reactance, respectively.

Since voltage and current no longer rise and fall together, a "PHASE SHIFT" is occurring in the circuit. Capacitance has the property of delaying changes in voltage as described in Module 4.3. That is, the applied voltage reaches steady state only after a time dictated by the time constant.
One of the most intriguing aspects of capacitor behavior is the 90-degree phase shift between the voltage across the capacitor and the current flowing through it. This
First look at my circuit. The voltage source has a value of 5V with a phase angle of zero, and the capacitor''s impedance is 5Ω. So the current is obviously 1A with a phase angle of 90°.

Capacitors aid in phase shift in AC circuits by storing and releasing energy, causing voltage and current to be out of phase. In alternating current (AC) circuits, the current and voltage typically rise and fall together. However, when a capacitor is introduced into the circuit, it alters this synchronisation, leading to a phase shift.

Therefore a phase shift is occurring in the capacitor, the amount of phase shift between voltage and current is +90° for a purely capacitive circuit, with the current LEADING the voltage. The opposite phase shift to an inductive circuit.
Since voltage and current no longer rise and fall together, a "PHASE SHIFT" is occurring in the circuit. Capacitance has the property of delaying changes in voltage as described in Module 4.3. That is, the applied voltage reaches steady state only after a time dictated by the time constant.
In this case, the phase shift starts at +90°, and the filter is a high-pass. Beyond the cutoff frequency, we eventually settle to 0°. So we see a series capacitor will always contribute between +90° and 0° phase shift. With this information at our disposal, we can apply an RC model to any circuit we wish.
The phase relationships created by inductors and capacitors are described using the words leading and lagging. In a DC system, a capacitor’s voltage reaches the maximum value after its current has reached the maximum value; in an AC system, we say that the capacitor creates a situation in which voltage lags current.
A shunt capacitor will cause between 0° and -90° phase shift on a resistive load. It’s important to be aware of the attenuation too, of course. A similar look at a series capacitor (for example, an AC-coupling cap) shows the typical effect for that configuration. Figure 3. Series capacitor circuit... Figure 4. And its bode plot
