Accepted Answer

Current from D to C = 1A
$ 	herefore $  V
D
Ã¢ÂÂ V
C
= 2 ÃÂ 1 = 2V
V
A
= 0   $ 	herefore $ V
C
= 1V,
$ 	herefore $ V
D
Ã¢ÂÂ V
C
= 2
$ \Rightarrow $ V
D
Ã¢ÂÂ 1 = 2    $ 	herefore $  V
D
= 3V
$ 	herefore $ V
D
Ã¢ÂÂ V
B
= 2   $ 	herefore $ 3 Ã¢ÂÂ V
B
= 2 $ 	herefore $ V
B
= 1V
