Observe the schematic symbol for each part. Make sure that you have all the parts ready before you begin Step 2.Step 2 – Build the CircuitUsing the Schematic Diagram and the picture of the completed lab, build the lab experiment with the electronic components.Step 3 – ExperimentProcedure:Assemble the circuit and connect a 9-volt battery to the Battery Snap. Break the circuit and use a multimeter to measure the current at each of the positions A-F indicated in the schematic diagram. Reconnect the circuit after each measurement and record your results. These measurements show the currents flowing into and out of each node. A node is any place where two or more conductors connect, You are most interested in nodes that are also “branch points” where 3 or more conductors connect.Observation:By measuring the currents that enter and exit each node, you have observed Kirchhoff’s Current Law which states that “The sum of the currents flowing out of a node equals the sum of the currents flowing into that node.”LAB 40Visit us online at www.ETronCircuit.com for more exciting projectsLab Observations
