Why does a capacitor create a 90 degree phase shift

Immediately after you turn on, the maximum current will be flowing, and the minimum voltage will be across the capacitor. As you wait, the current will reduce as the capacitor charges up, but the voltage will increase.

For an ideal capacitor, when is the current leading and when is

The current through a capacitor always leads the voltage across the capacitor by 90 degrees. The current through a resistor is always in phase with the voltage across the resistor. The voltage across elements in parallel must be the same. The current through elements in series must be the same. These are the rules...apply as necessary.

Why Current Lead in capacitor and lags in inductor?

As the capacitor current is proportional to its terminal voltage derivative (i=c(dv/dt)) the sine wave of voltage produces a cosine wave current in it. A similar reason can be applied for the

Voltage lags current: a physical interpretation

Capacitor: voltage lags current. This is not the case with a capacitor. A capacitor is specially constructed and isn''t all just a single conductor. It switches from conductor to dielectric to conductor. Conductors and dielectrics differ in how electrons move. In a conductor, electrons are free as the wind, all they need to move is some

Leading and lagging current are phenomena that occur as a result of alternating current. In a circuit with alternating current, the value of voltage and current vary sinusoidally. In this type of circuit, the terms lead, lag, and in phase are used to describe current with reference to voltage.
