AC vs DC: The Lethal Debate of Constant Voltage

  • Thread starter hellraiser
  • Start date
In summary, the conversation discusses the dangers of AC and DC currents and the difference between voltage and current in causing fatalities. It is mentioned that AC has a higher potential to cause heart fibrillation, while DC is generally considered safer. The use of high voltage in a van der graff generator is also mentioned as an example.

Which one is more lethal?
AC or DC.
The value of AC rms is given to be equal to DC.
I think it ought to be DC because it would provide constant voltage. but in case of ac it drops to zero sometimes. I would have exprimented but... :rofl:

Think about what is dangerous. Is it the voltage or the current that kills you?
 
  • #3
it is the current that kills

That's an interesting question. Here some info you might find useful

I don't know what this question is specifically asking? Dead is dead, no matter what killed you...

The van der graff generator kids play with in high school uses thousands of volts with a tiny current.

Certain AC current levels cause heart fibrilation (higher levels cause a heart contraction and release,as in a de-fibrilator, not fibrilation) , if the current passes through the heart. That is what usually does the killing. DC is way safer in comparison.
 

1. What is the difference between AC and DC?

AC (alternating current) and DC (direct current) are two types of electrical currents. AC changes direction periodically, while DC flows in only one direction.

2. Which is more commonly used, AC or DC?

AC is more commonly used in households and commercial buildings, while DC is mostly used in electronics and batteries.

3. Is one type of current more dangerous than the other?

Both AC and DC can be dangerous if handled improperly. However, AC is more likely to cause severe electrical shock due to its ability to travel longer distances and affect the heart's rhythm.

4. Why is AC preferred for long-distance power transmission?

AC can be easily converted to higher or lower voltages using transformers, making it more efficient for long-distance power transmission. DC would require expensive and bulky equipment for the same purpose.

5. Which type of current is better for electronic devices?

Most electronic devices operate on DC, so AC must be converted to DC through a power adapter. However, some devices, such as motors, require AC to function.
