Why potatoes can generate electricity? Electric current is conducted between two metals inserted in the potato by forming a salt bridge between them. This occurs because the salt in the potato releases ions, allowing them to travel through the wire connecting the two metals[sc:1][sc:comma][sc:2]. In short, a potato can act as a battery.
Do air conditioners use electricity when off? Your AC will actually run longer overall if it is left on all day instead of being shut off.
