Main Question or Discussion Point
what is difference between an electric cell and a battery?
I think 'loads of them in series' would collectively be referred to as a solar panel, where multiple panels could further be assembled into a solar array. But with 20 years as a science teacher, you already knew this, so I'm not sure why I even bother writing this. Have a nice day :)Interestingly enough, we always talk of Photovoltaic / solar Cells not batteries - even when we use loads of them in series.
You've been watching too much Nick Park.p.s. what about Battery Hens?????
