According to the loop shown for Kirchhoff's Voltage Law, which expression is written for the closed circuit? 
A$V_1+V_2+V_3+V_4+V_5+V_6+V_7=0$
B$V_1+V_2+V_3+V_4+V_5+V_6+V_7-V_5=0$
C$V_1+V_2+V_3-V_4+V_5+V_6=V_7$
D$V_s=V_1+V_2+V_3+V_4$
Answer & Solution
Correct answer: B. $V_1+V_2+V_3+V_4+V_5+V_6+V_7-V_5=0$
The page explicitly gives the Kirchhoff's Voltage Law relation for the shown loop as $V_1+V_2+V_3+V_4+V_5+V_6+V_7-V_5=0$. The question asks for the expression written for that loop, so option B matches the provided content.
