In the circuit shown, in the figure, what is the value of delta V14?

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]

  • first 2 are right

  • (C)1.3V rounded
