Prerequisites

Lab Activities

Students use a multimeter to measure voltages, currents and resistances for three different resistive circuits and compare these results to the values predicted by the application of Ohm's law, the equivalent resistance relationships, and Kirchoff's node and loop rules to the circuits. Experimental values tend to be within 5-10% of the theoretically predicted values.
