Problem 4.1: Calculate the equivalent resistance of the following resistors as seen by the voltage source
V_(in), such that you could replace the following circuit with the simplified circuit below. Assume the following values:
V_(in )=10V,R_(1)=5k\Omega ,R_(2)=9k\Omega ,R_(3)=5k\Omega ,R_(4)=2k\Omega , and
R_(5)=1k\Omega . Give your answer in units of
k\Omega .
