You buy a 60W lightbulb in Europe, where electricity is delivered to homes at 240V. If you use the lightbulb at home in the United States, how bright will it be relative to 60W 110V bulbs? Calculate how much power it will consume.© BrainMass Inc. brainmass.com February 24, 2021, 2:18 pm ad1c9bdddf
First we need to calculate the resistor of this 60W/240V lighbulb, say R. By a formulae "Power=Voltage*Voltage/Resistor", so we have
Similarly, we know that the resistor ...
The solution is given as a described equation. The expert determines how bright the relative bulbs will be and how much power will be consumed.
