Rectification.
a device which changes ac to dc is known as 'conevrter' a device which changes dc to ac is known as 'inverter'
A Cobra power inverter changes direct current (DC) to alternating current (AC). It takes battery power and inverts it so that common household appliances can use the power.
AC Power is Alternating Current whereas DC Power is Direct Current.
DC
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.
A transformer changes the VOLTAGE of AC current (AC to AC). A rectifier changes AC to DC.
AC power is made by alternating current and DC does not change.
You can plug an AC computer into a DC plug only if you also have an inverter to transform the DC power into the AC power that the computer power supply expects.
A DC/AC power inverter is used to convert DC, the power that comes from a car's battery, into AC, the kind of power that is supplied to a home and used to power larger electronics.
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of 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.
