    Re: problem

    You've posted this in the wrong forum. There are homework forums for that. You only need to work out the current in each parallel branch, bearing in mind that the voltage across parallel elements are the same. Then with the current, you can find the potential difference and hence Va and Vb. Then with both Va and Vb you can find Vab.
