second part of the experiment, we connected two long red and black wires the light bulbs in place of a resistor and recorded the data for each series. For the Light bulb part, there were four different figures: Single light bulb, light bulb A and B in series, light bulb A and B in parallel, series parallel light bulb.Equipment:AC/DC Electronics Laboratory Short Patch cords (set of 8) 850 Universal interfacesPASCO capstoneLong wires lab manual: Series and Parallel Circuits 1.Set DC waveform at 15 voltages, click auto, click signal generator to close panel,click record. 2.Applying Ohms Law: R=V/I3.Calculate the percent difference between theoretical Req and Measured Req for table three. Lab manual: Light Bulb1.Attach two long wires from the red and black leads to light bulb. 2.Open the signal generator and set the waveform for a triangle wave at 10Hz and amplitude for 2.5 voltage. Then click auto then close the signal generator. 3.Click record, then stop. Select the data and apply a linear fit, won’t be completelylinear because of the bulb resistance change as it heats and cools. 4.Enter the values of the slope, 0.1 for the bulb. Record each data. Repeated for each.
