What things use AC (alternating current) electricity

[HFS+]

ok i know mostly everything digital uses DC electricity but what uses AC electriticy?

Your mom's vibrator. She has the special 120VAC wall plug-in model.

To prove the danger of AC electricity and its suitability for executions, Brown and Edison publicly killed many animals with AC for the press in hopes of associating alternating current with electrical death.

The first person to be executed by the electric chair was William Kemmler in New York's Auburn Prison on August 6, 1890; the "state electrician" was Edwin F. Davis. The first 17-second passage of current through Kemmler caused unconsciousness, but failed to stop his heart and breathing. The attending physicians, Edward Charles Spitzka and Charles F. Macdonald, came forward to examine Kemmler. After confirming Kemmler was still alive, Spitzka reportedly called out, "Have the current turned on again, quick, no delay." The generator needed time to re-charge, however. In the second attempt, Kemmler was shocked with 2,000 volts. Blood vessels under the skin ruptured and bled, and the areas around the electrodes singed. The entire execution took about eight minutes. George Westinghouse later commented that "they would have done better using an axe,"[7] and a witnessing reporter claimed that it was "an awful spectacle, far worse than hanging."

Almost every single electrical appliance/equipment in you house/work used it.

I'm assuming you mean:
"What uses AC?, not including devices that convert mains power to DC before it goes to the primary circuit of said device."
Answer: a LOT of shit.

Do you remember which TV you watched the Patriots lose to the Giants on? Yeah, that one uses AC electricity

light bulbs, ac motors, heaters

Lights. Air conditioners. Other appliances.

Some things are hybrid AC/DC devices. My oven is electric, the heating coils are AC, but the display and timer, etc., are all DC - there's a little transformer inside and it uses a backup battery to keep the clock timing just like my alarm clock.

Smoke Detectors are also mains-powered with a DC backup battery.

When you post a thread, do you actually ever respond to your thread?

light bulbs, ac motors, heaters

Transformers, Some Capacitors, Vacuum Tubes...

 

[DrPizza]

Some of those devices mentioned earlier in the thread actually convert the AC to DC before using it.

Vegetables run on AC electricity.

yes, for sure. but not the electric chair

Potatoes make DC though... I'm confused now.

it obviously has a rectifying function

potatoes are a starch

Some electric motors, lightbulbs, heating elements, clocks, etc.

The reason that we primarily use AC as opposed to DC is that transmission over longer distances is more economical with AC. DC is better suited for end use, which is why we usually convert back to DC for many of the devices we use.

WRONG.

DC is better for everything, except killing elephants. Ask Edison.
