Question

Consider the following figure.

An open circuit containing four resistors starts at point a and ends at point b. The circuit extends up and to the right from point a to a 4.00 Ω resistor. The circuit then extends to the right to point c, where it splits into two parallel horizontal branches. There is a 7.00 Ω resistor on the top branch and a resistor of resistance R on the bottom branch. The branches then recombine to meet at point d. The circuit extends to the right from point d to a 9.00 Ω resistor. The circuit then continues to the right and down until it reaches point b.
(a) Find the equivalent resistance between points a and b in the figure. (R = 15.0 Ω)
