Which would be more dangerous for a human being 230 V a.c or 230 V dc supply...
Not really, at higher frequencies AC travels in the surface of a conductor (the skin effect) but that's not relevant here.Carlos Dutra said: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?
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.
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.
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.
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.
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.
