Response to the following problem :
Parts (a), (b), and (c) of this problem should be done by inspection-that is, mentally. The intent is to obtain a solution without a lengthy series of calculations. For the network of Fig.
a. What is the approximate value of I1 considering the magnitude of the parallel elements?
b. What are the ratios I1/I2 and I3 /I4?
c. What are the ratios I2 /I3 and I1/I4?
d. Calculate the current I1, and compare it to the result of part (a).
e. Determine the current I4 and calculate the ratio I1/I4. How does the ratio compare to the result of part (c)?
