It's just resistance, expanded into the complex domain because the 'resistance' of capacitors and inductors is frequency dependent and therefore better represented by imaginary numbers.

If you understand resistance, you understand impedance.

I and U are both sine waves.
You want a proportionality factor between them.
The usual resistance R is simply I*R=U
This means the sine waves I and U are equal, except for a constant factor that effects the amplitude.
The reactance X acts as a phase shift between U and I.
