Overview

A basic electric circuit will be simulated, consisting of a power supply, ammeter, resistors, and wiring. Using this circuit simulation, students will do several sets of measurements and plot those data. First, while keeping the resistance constant, voltage will be varied and its effect on electric current measured with an ammeter. Students should collect enough different voltages so they can sketch a graph. The plots will suggest the relationship between current, voltage and resistance, and can be used to justify Ohm’s law.
