Options:
A) $ 1500V $
B) $ 1000\ V $
C) $ 500\ V $
D) $ 400\ V $
Show Answer
Answer:
Correct Answer: C
Solution:
The given circuit can be redrawn as follows
$ (V _{A}-V _{B})=( \frac{15}{5+15} )\times 2000 $
therefore $ V _{A}-V _{B}=1500V $
therefore $ 2000-V _{B}=1500V $
therefore $ V _{B}=500V $
