Phase Delay of capacitor's voltage

[kehler]

Does anyone know why increasing the frequency of a RC circuit increases the phase delay in the capacitor's voltage (with respect to the voltage of the source)?
I understand that the amplitude decreases because the impedance increases but I don't understand why the phase delay increases :S

Any help would be appreciated :)

An RC circuit has a complex impedance that depends on frequency. As frequency changes, the modulus and phase of the impedance changes too.
Write the complex impedance and calculate both modulus and phase.

The phase delay in a capacitor's voltage is caused by the reactive component of the circuit, which is the capacitor itself. At low frequencies, the capacitor acts like an open circuit and does not allow current to flow through it. As the frequency increases, the capacitor starts to behave more like a short circuit, allowing more current to flow through it.

This increase in current causes a phase shift between the voltage across the capacitor and the voltage across the source. This means that the capacitor's voltage "lags" behind the source voltage, resulting in a phase delay.

Additionally, as you mentioned, the impedance (or resistance) of the circuit also plays a role in the phase delay. At higher frequencies, the impedance of the capacitor increases, causing a larger voltage drop across it and further increasing the phase delay.

In summary, the phase delay in a capacitor's voltage is a result of the capacitor's reactive behavior and the increase in impedance at higher frequencies. I hope this helps to clarify the concept.
