Calculations
For each junction, calculate the sum of the currents entering
the node and the sum of the currents leaving the node. If the sums
equal each other, then the First Kirchhoff’s Rule
is verified. Find the percent difference between these sums.
This percent difference shows the experimental error of your
measurements.
Calculate algebraic sum of the voltages for each loop. If the
sums equal zero, the Second Kirchhoff’s Rule is verified. For
each loop, calculate algebraic sum of the voltages on
the batteries and compare it with the algebraic sum of the
voltages on resistors. Find percent difference between the
magnitudes of these sums. This percent difference shows the
experimental error of your measurements.
Using the Second Kirchhoff’s Rule and the sign convention
(Table I) develop the equations for each closed loop of Fig. 9a, 10
and 11 respectively. Substitute the corresponding values of
