Batteries are DC current.
Batteries provide Direct Current (DC) while household outlets provide Alternating Current (AC).
Not directing current but DIRECT current, meaning there is no oscillation in the current.
DC
Batteries have chemical energy stored inside them. Of course, when they provide a current, this chemical energy is transformed (in part) into electrical energy.
Batteries and generators provide DC, Direct Current electricity.
They both provide an electrical current.
direct current
A Direct Current, DC.
All batteries provide DC. It does not matter their makeup.
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
A way of connecting batteries together to provide more current is to connect them in parallel. This allows more capacity at the same voltage. If the batteries were connected in series the voltage would be increased.
How Automotive Batteries Create Electrical CurrentAutomotive batteries create electrical current by converting chemical energy stored in the plates and the electrolyte [the Sulphuric Acid in auto batteries] to electrical energy.
