For parallel RC circuit phase angle is nothing but tan inverse (-wXcR). So we will get 34.8°

Always remember that phase angle is referenced at Irms' angle. Try to divide Vrms to Ztotal.

They asked to find phase angle for parallel circuit tan^1 (-wXcR) = 34.8°.

In series RC Theta = tan inv (XC/R).
In Parallel RC Theta = tan inv(R/XC).

It should be -34.8 means voltage is lagging because it has a capacitor.

How is the 34. 8 answer is right ?
What is the formula ?

Why arctan(-xc/R)? why shouldn't we do arctan(xc/R)?

Lalu said:   1 decade ago
for parallel circuit tan-1(Ic/Ir)
Ic=V/Xc
Ir= V/R

Calculate xc then tan inverse (-xc/R).

The ans will be -34.8.
