SUMMARY

In an RC circuit, a capacitor acts as a phase shifter for AC voltage by causing the current to lag behind the voltage. As the capacitor charges, the circuit's current decreases, resulting in an offset between voltage and current. This phase shift occurs due to the relationship defined by the formula involving resistance (R), capacitance (C), and frequency (w). Understanding this behavior is crucial for applications involving AC circuits.

hi ..
I want a full explanation about using the capacitor as phase shifter for AC voltage as I don't know any thing about this application of the capacitor.
pleasssssssssssssssse help me .
&
thanks in advance...

With a capacitor its charge builds faster with higher voltage, and as charge builds the circuit's current decreases, so as the voltage increases the current decreases, then as the voltage decreases vise versa happens so now the voltage and current are offset. The original currents was in-phase with the voltage so when the current gets out of phase with the voltage the two currents are now out of phase.
