Form 3 learnerWhy does a car battery go flat if I leave the lights on?
HenissThink of the battery as a tank of stored chemical energy. The lights turn it into light and heat, a little every second. With the engine off, nothing is refilling the tank, so after a few hours there isn't enough left to turn the starter motor. Want to work out how long it would take, using Ohm's law?
