In the circuit element given here, if the potential at point `B = V_(B) = 0`, then the potentials of `A` and `D` are given as

Options

A. `V_(A) = -1.5 V, V_(0) = +2 V`
B. `V_(A) = +1.5 V, V_(D) = +2 V`
C. `V_(A) = +1.5 V, V_(D) = +0.5 V`
D. `V_(A) = +1.5 V, V_(D) = -0.5 V`

Answer

D

Explanation

`V_(A) = 1.5 xx 1 = 1.5 V,V_(C ) = -2.5 xx 1 = -2.5 V`
`V_( C) + 2 = V_(D) rArr V_(D) = -2.5 + 2 = -0.5 V`
