Dear Kesava Pillai Sir,
Thank you for participating in the thread. You have provided a simple example to help understand the theory of electricity.
From your reply, it is clear that 24V cannot kill a person or induce Ventricular Fibrillation. I would like to request clarifications on the following concerns:
If the human body resistance is 1000 Ohms (in wet conditions) and 24 mA of current flows through the human body at 24V (with the heart in the circuit), how safe is a person in this scenario? How long can this current flow through the human body without causing Ventricular Fibrillation? Is 24V safe for the human body in this situation?
I am unsure if this is a foolish question. If not, I believe that asking questions is crucial for learning. Have you encountered or heard of any cases during your career where 24V has caused death to an individual?
I look forward to hearing from you soon. Thank you in advance.

Dear Mr. Dipil,
I am still unable to understand the concepts of Current, Voltage, and Ampere. Even though the Power supply is 24 Volts, if the amperage is high, it can be fatal for a person. This was mentioned by an electrical engineer, but I am struggling to comprehend it. There are many things in this world that we cannot comprehend, and this is just one of them. I look forward to hearing from our knowledgeable members.
Regarding Ohm's Law, where I = V/R (current = voltage / resistance), we can infer that current is directly proportional to voltage and inversely proportional to the body's resistance. These three factors play a crucial role in causing electric shocks to humans. Voltage represents pressure, current symbolizes the flow of electrons, and resistance signifies the stability of the human body. The minimum current required for electrocution is 10 milliamps.
For example, if the voltage is 24 volts and the human body's resistance is 100 ohms, what would be the current?
I = V/R
= 24/100
= 0.24 amps, and so forth.
Here's another analogy: Picture a water tank with its outlet connected to a pipe and a tap. The pressure inside the tank is akin to voltage, and the flow of water through the pipe is comparable to current.
Thank you.
