The energy source should be a standard 150W light bulb connected to the 230V mains.
How can I set up solar cell to measure the power output of the cell? and how to set up the experiment to measure the rate of heating of water by the bulb?Which one is more efficient?
Comparing the energy conversion rates of solar cell ang solar panel?
