If high voltage is so dangerous, why do we transmit electricity that way?
Transmitting power at higher voltages ensures that power can be transmitted over long distances with minimal losses; if transferred at a low voltage, the transmission distance has to be greatly minimized, which is impractical.Read More...

Keywords: Lend an Experiment (LEx), photovoltaic cell, photovoltaics, resistance, solar, solar cells, solar energy
Did you know that the amount of power from a solar panel depends on what it's connected to? Explore how photovoltaic panels work, converting light into electrical energy, and learn how you can find the maximum power output from a solar panel.
This activity is part of the LEx (Lend an Experiment) Climate Kit. Students use solar panels to generate electrical power, exploring how light energy can be turned into electricity. Students connect the photovoltaic cells to different loads to find their peak power output.Read More...
