Procedure: In the lab, we try to know how much voltage and current that the battery and the ideal source supply to fan and lamp. After we got the data for the voltage and current, we can calculate the how much power that the battery and the ideal source supply to fan and lamp. We used AC/DC inverter to change the battery and the ideal source’s voltage from DC to AC. We connected DMM in parallel to record the voltage and multi-meter in series to record the current. Data Table: VL IL P out RL RS P loss Efficiency Fan off 12.4V 0.3A 3.72W 41.3Ω 42Ω 3.78W 0.496 Fan low 11.8V 2.82A 33.276W 4.18Ω 4.468 Ω 35.531W 0.484 Fan medium 11.7V 3.3A 38.61W 3.545Ω 3.316 Ω 36.111W 0.517 Fan high 11.6V 3.8A 44.08W 3.503Ω 3.316 Ω 47.833W 0.479 Lamp off 12.3V 0.28A 3.444W 43.93Ω 45Ω 3.528W 0.494 Lamp on 11.5V 4.52A 51.98W 2.544Ω 2.788 Ω 56.96W 0.477 VL IL P out RL RS P loss Efficiency Fan off 12.2V 0.28
