Name two sources of AC and DC.

Two sources of AC (Alternating Current) are power plants and generators, while two sources of DC (Direct Current) are batteries and solar cells.

Sources of AC

• Power Stations: Electricity supplied to homes is AC, generated in power plants.
• Alternators: Used in vehicles to generate AC for charging batteries.

Sources of DC

• Batteries: Provide DC for devices like torches and remote controls.
• Solar Cells: Convert sunlight into direct current for use in homes and gadgets.

In short, AC is used for transmission over long distances, while DC powers small devices directly.
