Parallel Circuit With FOUR Lamps

1. The document provides instructions for students to construct a parallel circuit with four lamps and test it using a multimeter. 2. Students are asked to draw the circuit diagram, build the physical circuit, and record voltage, current, resistance, and wattage readings for each lamp both individually and for the total circuit. 3. By removing one lamp, students can observe how the circuit behaves and note any changes in the other lamps to understand Kirchhoff's laws and the differences between parallel and series circuits.
