Question

10. For the circuit shown in figure, determine the unknown voltage drop V1.
+2V-
+V
30V
w
-3V
--SV+​

Answer 1

Answer:

19A

Explanation:

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
