DC Circuits: Electric Power By: Rory McPherson TA Jie Zhang Lab Partners: Mike Russell, Andrew Wallach
Objective: Determine the load resistance number at which the power is optimized in a DC circuit experimentally. Procedure: R 0 was measured directly using the DMM in ohms keeping in mind to remove the effective internal resistance. The DC circuit was connected as I an V values were taken for increasing load resistance. The load resistance was increased in increments of 10 ohms from 10-100, then 20 ohms from 120-200, and then 100 ohms from 300-100. The power dissipated by the resistor was calculated for each value and a graph of power vs. load resistance was made. Using the graph, and the load resistance, a max power output was found. This was done with a load resistance of 100 ohms and 200 ohms. Results: R 0 = 100 Ohms – R L,max = 120 Ohms – P
