), load resistor (R L ), ammeter, and voltmeter. The equation ࠵? = K L M L NM O - ∗ ࠵? , gives the power dissipated in the load resistor. R 0 was measured to be 100 Ω and then current-voltage data was recorded as the value of R L was changed. R L was in increments of 10 Ω from 10-120 Ω ; increments of 20 Ω from 120-200 Ω ; and increments of 100 Ω from 200-1000 Ω . The power dissipated was calculated with the equation ࠵? = ࠵? ∗ ࠵? and a graph of P vs. R L was plotted. The graph was fitted to the form ࠵? ∗ J PN3 - . The load resistance that maximizes power output was roughly 110 Ω . The calculated efficiency of our circuit was 52.36%. One source of error for our group was that for part 2 we used a different value of V 0 which still worked but, changed our numbers and results from the rest of the groups. Another source of error could come from improperly setting up the circuit and measuring the wrong values. It’s important to follow the directions and set things up in the right order.
