What does it really take to power a light bulb?
This activity is part of the LEx (Lend an Experiment) Climate Kit. Students compare the power consumption of incandescent and LED bulbs through the use of hand crank generators and a simple circuit. Concepts include the conversion of mechanical to electrical energy, power and efficiency, and measurement estimation. There is an option to also investigate the efficiency of the hand crank generator.Read More...
