|I= sq root (Ir^2+Ic^2)
so I= sq root (0.785^2 + 4.508^2)

where 11 is a number
You can take any number in that place.

|Current across the capctor leads the current across the resistor by 90 in phase diagram.

|Why square rooting Ir & Ic?|
|Jjc said: (Jul 29, 2017)|
|Ir and Ic are not in phase (90 degrees out of phase).
In a graphical analysis, they will form a right triangle, the longest side (hypotenuse) is the total current (geometric sum), which can be solved by using the Pythagorean theorem. It=sqrt(Ir^2 + Ic^2).
