I am studying electrical engineerin 1

I am studying electrical engineering and need to justify a phenominum. When I calculate the impedance of a 2 branch parallel circuit containing a coil with a resistance in branch 1 and a power factor correction capacitor in branch 2. When I calculate the current total is the current phase angle always 0 degrees?

No. Resistance phase angle is zero.
Capacitor phase angel is leading 90 degrees.
Pythagoras tells us to use I total = √{(resistance current)² + (capacitor current)²}
eg. for 10 Amps through the resistance and 10 Amps through the capacitor, the total current will be
√(10 Amps resistance current)² plus (10 Amps capacitor current)²
√{{10 x 10) + (10 x 10)= 200
√200 = 14.14 Amps total current. (corrected)

Not just a good idea;
It's the LAW!
