No voltage across this component

kirchhoffs-lawsvoltage

There is a Problem in our textbook which asks us to find, using Kirchoff's law, the voltage across component v_x and v_y.

According

I know that the voltage at node 1 should be 14 volts from [21 + (-7)]=14 (in terms of $$v=\frac{dw}{dq}$$
not in terms just of potential difference.

The voltage across V-x is 9 because the voltage across the two components in series right below it is 5.

Of course, v_y is 14. This said:

Is there going to be any voltage across the rightmost component?

I'm going to assume you meant "rightmost" since the leftmost component is a supply.

The voltage across the rightmost component must be the same as any components in parallel. Hence, it has 5V across it.
