What type of current is used for coffe maker?

Coffee makers typically use alternating current (AC). AC current is the type of electrical current that flows in household outlets and powers most electrical appliances. It is characterized by its waveform, which alternates between positive and negative values. This alternation creates a constantly changing flow of electrons, which is necessary for powering most electrical devices.

Direct current (DC), on the other hand, is a type of electrical current that flows in one direction only. It is commonly used in electronic devices such as batteries and computers. While some coffee makers may have internal components that use DC current, the overall power supply for the appliance typically comes from an AC source.
