Extracted text: 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.

Is the main current (I) equal to sum of currents In and I2? Check for all steps. c. Calculate the equivalent resistance R of the circuit. Req = ... d. Calculate main current (I) for all steps by using the Ohm's Law. Compare the results with the results calculated by using Kirchhoff s Current Law in step b. e. Check your calculation in step c by measuring overall resistance using an ohmmeter.
