PROBLEM 1.17 KNOWN: Data of form y = axb. FIND: a and b; K SOLUTION
The data are plotted below. If y = axb, then in log-log format the data will take the linear form log y = log a + b log x A more or less linear curve results with this data. From the
KNOWN: Four resistors are available: two rated at R = 500 50 and two rated at R = 2000 5% .
FIND: Best design combination to form RT = 1000 SOLUTION We can combine the resistors in series or in parallel. Consider as Case 1, a series
PROBLEM 11.6 KNOWN: A Wheatstone bridge with all resistances initially equal to 100 . The
