Consider the potential difference between pairs of points. Let delta Vab be the magnitude of the potential difference between any two points, point a and point b.
a) In the circuit shown in (Figure 1) , what is the value of delta V14?
b) In the circuit shown in (Figure 1) , what is the value of delta V24?
c) In the circuit shown in (Figure 1) , what is the value of delta V34?
here is the link to the figure for the problem: http://session.masteringphysics.com/problemAsset/1…

R2to4= 10/2= 5Ω
R1to4= 10/2= 5Ω
REto4= 5+5= 10Ω (Equivalent resistance)
voltage divider
(a) v14= 10*5/(5+5)= 5[V]
(b) v24= 5*5/(5+5)= 2.5[V]
(c) v34= 2.5*5/(5+5)= 1.25[V]
