    Ac Dc
In summary, both 230 V a.c and 230 V dc supply can be dangerous for humans, assuming enough current. However, people often believe that DC is more lethal and painful because it runs through the center, while AC is concentrated around the conductor. This is not entirely true, as at higher frequencies AC travels in the surface of a conductor. AC can kill at very low currents because it affects the heart's electrical signals, while DC kills by burning and requires higher current. However, high power DC can be more dangerous in use because it is difficult to switch off or disconnect.

Which would be more dangerous for a human being 230 V a.c or 230 V dc supply...

Assuming enough current both can kill you.

People say that the DC is more lethal and painful because it runs through the center, while the AC is concentrated around of the conductor.

does anyone know if it's true?

Not really, at higher frequencies AC travels in the surface of a conductor (the skin effect) but that's not relevant here.

AC can kill you at very low currents (0.01A) because the heart uses electrical signals. A small 50/60Hz AC current through the heart causes it to try and beat at 50/60 times per second which doesn't work for very long.

DC kills you be simply burning so you need a lot more current.

But high power DC can be a lot more dangerous in use. It's very difficult to switch off DC or disconnect something that is attached to it.
 

1. What is the difference between 230 V AC and 230 V DC?

230 V AC (alternating current) refers to the type of electrical current that flows in two directions, constantly changing its direction and magnitude. On the other hand, 230 V DC (direct current) refers to the type of electrical current that flows in one direction with a constant magnitude.

2. Which type of current, 230 V AC or 230 V DC, is more commonly used in households?

230 V AC is more commonly used in households because it is the type of current that is supplied by the power grid. Most household appliances and electronics are designed to work with AC current.

3. Is one type of current, 230 V AC or 230 V DC, more dangerous than the other?

Both types of current can be dangerous if not handled properly. However, 230 V AC is generally considered more dangerous because it can cause muscle contractions and heart fibrillations, whereas 230 V DC can cause burns and nerve damage.

4. Can 230 V AC and 230 V DC be interchanged without any consequences?

No, it is not safe to interchange 230 V AC and 230 V DC without proper precautions and equipment. Most devices and appliances are designed to work with a specific type of current and using the wrong type can damage the device or cause harm to the user.

5. How can I protect myself from the potential dangers of 230 V AC and 230 V DC?

To protect yourself from the dangers of 230 V AC and 230 V DC, always follow safety precautions and use proper equipment when working with electricity. This includes wearing insulated gloves and using a ground fault circuit interrupter (GFCI) when working with 230 V AC, and using proper insulation and avoiding direct contact with 230 V DC.
