Calculating Phase shifts of componets (capacitors & inductors)
Calculating Phase shifts of componets (capacitors & inductors)
(OP)
does anyone know the formula to to calculate the phase shifts over capacitors and inductors? to be used in a computer program.
we know the values of components, type, frequency and current through each component. but NOT the voltage.
Thanks

1. Laplace transform
2. Fourier Transform
3. Z-transform
4. Hilbert transform
5. Etc.
to describe the model circuit in the frequency domain and then invert it to the time domain where it will show a phase shift, if it exists.
Voltages are:
1. capacitor Vc=(1/C) x Integral from 0 to T of Ic dt + Vco
2. inductor Vind=L x (di/dt)
3. resistor Vr=I x R
Note: Initial conditions of elements should not be overlooked.

You need to know any waveform has the equvalence to a series of sine wave with different frequency and phase angle. If your waveform is not perfect, The calculation will has error. The easy understanding example is square wave. By matematics, a square wave contain a lot of component with different frequency. If you just consider it is a simple sine wave the calculation will not work.
Also, the capacitor and inductor in high frequency need to consider the resistant on it.
I suggest you read a basic circuit textbook. It is easy to calculate.
I hope it help.
