„Well, according to our sketch electric power has something to do with voltage and amperage. Right?“
„I think so, Fred. Just think about how a hydropower station works! The more water runs through the turbine and the higher the pressure of the water the higher is the power the hydropower station can supply.“
„Ah, I get what you mean! Water pressure is like voltage and the amount of water running through the turbine stands for amperage.“
„How can we apply our idea on the light bulb? In a hydropower station the energy of the river current is transformed in electrical energy. And what happens in our electrical circuit?“
„Hm, well in our circuit energy is stored in the battery and electrical energy is ready. This electrical energy is then transformed into light energy in the light bulb.“
