− | {{w| | + | In electronics, {{w|direct current}} is a constant flow of electrons from a power source to something being powered, before doubling back along the circuit. It is commonly used for battery-powered appliances. {{w|Alternating current}}, on the other hand, frequently reverses the flow of electrons, and is commonly used for longer-distance use (such as from the power plant to an outlet). |

This is funny because since typical {{w|power inverter}} efficiency is 90%, and maximum {{w|bridge rectifier}} efficiency is 81.2%, an {{w|extension cord}} made of them would lose about 27% power per such pair. |

Rather, a separate device, a {{w|rectifier}}, also pictured in the comic, must be used for this second conversion. |
