The hypotenuse of the right triangle of a vector diagram for R and XC, is it the impedance?
1 Answer
Resistance is the limitation to charge mobility due to the material through which charges can travel. Capacitance is just the capacitor's ability to store charge before it needs to release that charge as current.
Impedance is like an "overall resistance".
I've seen Impedance written as
So yes, the hypotenuse of the vector diagram of this would be the impedance, when the phase shift
