Multiple Choice Options
- A 4 volt
- B 8 volt
- C 10 volt
- D 2 volt
Step-by-Step Verified Solution
We have,
P = V 2 R
_ 36 = V 2 9
_ V = 18
Current passing through the 9 � resistor is
i 1 = V R = 18 9 = 2 A
The 9 � and 6 � resistors are in parallel, therefore
i 1 = 6 9 + 6 _ i
where i is the current delivered by the battery.
_ i = 2 _ 15 6 = 5 A
Thus, potential difference across 2 � resistor is
V = iR = 5 _ 2 = 10V
