DC current passes through inverter resistor

DC current passes through inverter resistor

When science teachers explain the basic idea of electricity to usas a flow of electrons, they're usually talking about directcurrent (DC). We learn that the electrons work a bit. . One of Tesla's legacies (and that of his business partner GeorgeWestinghouse, boss of the Westinghouse Electrical Company) is thatmost of the appliances we have in our homes are specifically designedto run from AC power. Appliances that need DC but. . If you simply switch a DC current on and off, or flip it back andforth so its direction keeps reversing, what you end up with is veryabrupt changes. . We've just had a very basic overview of inverters—and now let's go over it again in a littlebit more detail. Imagine you're a DC battery and someone taps you on the shoulderand asks you to produce AC instead. How would you do it? If all thecurrent you. . Inverters can be very big and hefty—especially if they have built-inbattery packs so they can work in a standalone way.. [pdf]
