In the circuit shown, in the figure, what is the value of delta V14?
"Consider the potential difference between pairs of points. Let ΔVab represent the magnitude of the potential difference between two points, a and b.
a) For the circuit shown in Figure 1, what is the value of ΔV14?
b) For the circuit shown in Figure 1, what is the value of ΔV24?
c) For the circuit shown in Figure 1, what is the value of ΔV34?
Here is the link to the figure associated with 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]
