i have a problem about RCL parallel circuit .

when we have a RCl circuit with applied sinsusoid currnet ,we make all parameters in circuit as complex number i mean make them phasors.

i study this formula in my book and i do not know how too proove it.

why quality factor in this circuit is the ratio of capacitor or indoctor current to applied current?

2. Relevant equations

Q=I(c)/I(s)=I(l)/I(s)

3. The attempt at a solution

with the help of impedence and I(C)=V/X(c) and I(s)=V/Z
