In the given figure, potential difference between A and B is [RPMT 2000]
A) 0
B) 5 volt
C) 10 volt
D) 15 volt
Correct Answer:
C
Solution :
Equivalent resistance \[R=10+\frac{10}{2}=15\,k\Omega \] Current i = \[\frac{30}{15}=2\times {{10}^{-3}}A\] Hence, potential difference between A and B \[V=\left( \frac{2\times {{10}^{-3}}}{2} \right)\times 10\times {{10}^{3}}=10\,Volt\text{.}\]
