Description

In the experiment P3.6.6.3, two identical incandescent light bulbs are operated with the same electrical power. One bulb is operated with DC voltage, the other with AC voltage. The equality of the power values is determined directly using the joule and wattmeter, and additionally by comparing the lamp brightness levels. This equality is reached when the DC voltage equals the RMS value of the AC voltage.
