A) \[20/7V\]
B) \[40/7V\]
C) \[10/7V\]
D) zero
Correct Answer: D
Solution :
From the given figure current through lower branch of the circuit (resistance are connected in series) Current drawn \[=\frac{Total\text{ }e.m.f}{Total\text{ }resistance}\] \[{{i}_{1}}=\frac{10}{4+3}=\frac{10}{7}amp.\] \[{{V}_{A}}-{{V}_{P}}=4\times {{i}_{1}}=4\times \frac{10}{7}=\frac{40}{7}\,volt.\]You need to login to perform this action.
