3.
Use the DMM to measure the total current flowing through the circuit. Similarly measure the
current flowing through each of 3 resistors. Record these measurements in Table 2.2.

Use the current divider rule to determine the current flowing through each of 3 resistors. Calculate the
sum of the currents flowing through all 3 resistors. Does this calculated sum agree with the measured
sum found in the previous step? Comment on the validity of Kirchhoff’s current law and the current
divider rule based on your measurement results.
