6.002 Demo #02 ( Load set up Demo#02.set ) KVL & KCL Agarwal Fall 00 Lecture 2 Purpose: This demo provides an example for KVL by measuring the voltages across components in a loop, and KCL by measuring the currents into a node. Nodal analysis is also compared with this example, by comparing measured values with calculated values. The circuit used is five resistors in a bridge topology, with an AC and a DC voltage source. The AC source is used for KCL, along with a field-sensing current meter. The DC source is used with a multimeter for the comparison with calculated values. Steps: 1. To show KVL, measure voltages around a loop and show that they sum to 0. 2. To show KCL, measure currents into a node and show that they sum to 0. Additionally, take the three loose wires (see figure), bunch them together, and use the field-sensing meter to show the current is 0 when all three wires are put into the ring together. Note:
