The voltage across last resistor is V. All resistors are unity. Then $V_{s}$ is given by
- A. 13 V
- B. 8 V
- C. 4 V
- D. None of these
Answer: B. 8 V
Explanation: We start from left, two same resistors are in series, so voltage drop is same across both the resistors and again sum of these resistors are parallel to 1 Ω resistor so equal voltage and proceed in the same way. So, $V_{s}=8~V$
