2. Kirchhoff's Curent Law (KCL)
Experimental Procedure
Design the circuit using resistors and power supply (battery) and make the necessary connections
as shown in Figure 2.
According to Kirchhoff's Current Law, sum of incoming and outgoing currents must equal each
other. The figure shows I entering the node while In and Iz are leaving the node so we must have
I-I1+I2.
