What type of current is supplied by wall outlets?

• A. Direct Current (DC)
• B. Alternating Current (AC)
• C. Static Current (SC)
• D. Dynamic Current (DC)

Answer: (B)

Wall outlets supply Alternating Current (AC) because this type of current is suitable for general power transmission and household use. AC is produced by generators and can easily be transformed to different voltage levels, making it efficient for long-distance transmission. The periodic reversal of direction in AC allows electrical energy to be efficiently distributed through power lines and used in most electrical devices in homes and businesses. Direct Current (DC), on the other hand, flows in only one direction and is commonly used in batteries and electronic devices. Static Current and Dynamic Current are not standard terms used in the context of electrical supply; therefore, they are not applicable in this situation. The availability of AC at wall outlets facilitates the operation of a wide range of appliances and equipment designed to work with this type of power.
