Using the measured values, determine whether the algebraic sum of the currents entering and leaving node A (Fig. 2.1) satisfies or approximate Kirchhoff’s Current Law for different values of R. Show the algebraic sum on the space provided below for each value of R. (The set of measured values satisfies KCL if the algebraic sum is less than 0.1 mA = 0.0001 A)
