Using KCL (Node-Voltage Method)
1) Assume all currents leave the node.
2) Assume that Node B is reference node (0 volts).

(Va-2)/(1+1)+(Va-4)/2+(Va-4)/(1+1)=0
3Va/2=10/2
Va=3.33 volts
Va-Vb=3.33-0=3.33 volts

3,33volts for the Va-Vb and you ?
You answer is correct.

Do you know how to check your work starting from your answer? That is a most valuable skill, if for no other reason in that it will keep you from submitting answers that you THINK are right but that actually aren't.

Indeed i am, but like any human, mistakes are our gold friends.
Not sure which post you are replying to. If mine, the question was very much in earnest. Do you know how to check your answer starting from the answer? Most students don't, sometimes because they were never shown that it is possible and in other cases because they don't see doing so has value.
