Electrical energy out of chemical energy.
he did not create a battery
from the battery
A battery no longer able to provide a chemical reaction to create a charge
Best to unplug it and then disconnect it from the battery. Reason being is that if you disconnect it from the battery first you will create a spark. That spark could ignite any fumes from the battery.
Maybe maybe not
Potential difference (voltage)
By itself it is not a battery. The sulfuric acid is used to create a chemical reaction that releases electrons in the battery that creates electricity.
You can create a human battery by using your own hands and metal plates. Your hands are coated in a thin layer of sweat, which is mostly water but also contains salt. When you make a human battery, the sweat acts as the electrolyte, with the metal plates acting as electrodes.
If your car has a battery and it's dead, you can call a friend who has some jumper cables. You can hook the jumper cables up to his battery and your car's battery. It should create electricity that will renew your battery. If your car does not have a battery, you would have to push it or get it towed.
A car battery is a device used to create power for your car. Without it the car wouldn't start.Inside the battery there is some type of acid (usual alkaline or lithium).
Because a battery gives off hydrogen gas when it is charging and discharging. Be careful not to create sparks around a battery especially when jumpering because hydrogen is volitile.
the battery will create energy to any thing that doesn't have battery. So get something that needs electricity and get jumper cables and them up
