The potential difference between points A and B from the figure is

Options

A. `2//3 V`
B. `8//9 V`
C. `4//3 V`
D. 2 V

Answer

A

Explanation

By Kirchhoff's voltage law, for branch ABCEA
`15l_(1)=2 implies l_(1)=(2)/(15)A`
For branch ADCEA,
`15l_(2)=2 implies l_(2)=(2)/(15)A`
`V_(AD)=l_(2)R=(2)/(15)xx5=(2)/(3)V`
