In the figure ε = 14.2 V, *R*_{1} = 1290 Ω, *R*_{2} = 3490 Ω, and *R*_{3} = 3650 Ω. What are the potential differences (in V) **(a)** *V*_{A} - *V*_{B}, **(b)** *V*_{B} - *V*_{C}, **(c)** *V*_{C} - *V*_{D}, and **(d)** *V*_{A} - *V*_{C}?

Step 1

By symmetry, in the circuit, we can say that the current in the equals resistance are the same. In** R**_{1 }there are a current of** I**_{1 }, in ** R**_{2} there are a current of **I**_{2} and in ** R**_{3 } there are **I**_{3}.

Step 2

Now, from the circuit we can find the currents :

Step 3

Further,...
