A Circuit Contains Three voltage sources of 10 V, 10 V, and 5 V in series. The overall voltage Vab is | Basic Electrical Engineering MCQ#19

by

Statement: A Circuit Contains Three voltage sources of 10 V, 10 V, and 5 V in series. The overall voltage Vab is:

  1. 15 V
  2. -15 V
  3. -25 V
  4. 25 V

Correct answer: 2. -15 V

Vab = -10 V – 10 V + 5 V = -15 V
