Question

In the circuit diagram below, all three resistors have the same resistance

1) Rank the voltage difference (in descending order) for each of these pairs of points:

V_BA
V_FC
V_DF
V_EF
V_CA

₂₎ Rank the actual value of the electrical potential (in descending order) for each of these points:

Point D
Point B
Point C
Point E
Point F

Answer 1

1

For this question, we consider the resistance value between the given points,

The resistance between EF and FC is same and maximum, so, the voltage difference is maximum for those pairs.

Next, the resistance between C and A is greater than other two, so, the second place in the descending order is CA pair.

The resistance between A and B is greater than that of FD, so, third place goes to AB.

The resistance between F and D is zero, so, the voltage drop is zero. Therefore, the order is,

V_EF=V_FC>V_CA>V_AB>V_FD

2

The potential starts decreasing from beginning point to ending point, so, the ranking is,

E>C>B>F>D
