Q1.	For the circuit shown in Fig. determine the unknown voltage drop V₁
A.	18 V [Wrong Answer]
B.	19 V [Correct Answer]
C.	20 V [Wrong Answer]
D.	21 V [Wrong Answer]
View Answer 19 -11 Explanation:- Answer : B Discuss it below : According to Kirchhoff's voltage law, the sum of the potential drops is equal to the sum of the potential rises; Therefore, 30 = 2 + 1 + V₁ + 3 + 5 or V₁ = 30 - 11 = 19 V Click here for more comments
