The voltage and the current between A and B points shown in the circuit are _____.

Options

  1. A24 V, 12 A
  2. B24 V, 4 A
  3. C18 V, 12 A
  4. D27 V, 4 A

Correct answer

B. 24 V, 4 A

Step-by-step solution

The four parallel branches between the common left node A and the common right node are all identical: each consists of a 27 V source in series with a 3 resistor. In the third branch, the two cells (14 V and 13 V ) aid each other, giving a net EMF of 14 + 13 = 27 V . Thevenin equivalent between A and B : Since all four branches have the same EMF and polarity in parallel: V_ th = 27 V The four 3 resistors in parallel give: R_ th = 3 4 = 0.75 Load branch (diagonal): The diagonal connecting A and B consists of two 3 r
