An alkaline battery's output is DC as is any battery.
Batteries are DC
dc in battery stands for direct current .ac is alternating current.
Typically DC is what you get in a battery and AC is what powers your house.
No. A battery is considered to be DC power.
Batteries can provide both AC (alternating current) or DC (direct current) power, depending on the type of device they are connected to. However, most batteries themselves supply DC power. Devices that require AC power typically use an inverter to convert the battery's DC power into AC power.
Televisions in buses can be either AC or DC current. It depends on whether the bus is using a DC to AC power convertor or an AC generator or DC power from the battery.
No, the battery is DC not AC.
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.
No, the pump runs on AC current the battery supplies DC current. Yes, but you will need an inverter to turn the DC current into AC current
dc - the voltage is a constant 12 volts nominally in a normal car battery.
Car electrical systems are DC, direct current.
