in this photo there is the circuit and the KVL of the solution(adsbygoogle = window.adsbygoogle || []).push({});

but when i tried to do the KVL

i go from the arc(3 lines represents potential zero)

in counter clockwise direction

so i get[tex] V_L + V_C+V_R-V_s=0[/tex]

when i go against the direction of a current the voltage is on PLUS

when in the voltage source i go from + to - we have -V_s

so where is my mistake

i cant figure out how to get to the expression they got from my expression

?
