Why shouldn't we catch the power outlet ⁉️⚡?

Many people know that catching electrical equipment while wet hands is "dangerous," but have you ever wondered... why is it dangerous?

.

When the light is sucked, an electric current passes through our body into the ground. According to * * Ohm's law V = IR * *, it is seen that the current (I) flows through the body more or less depending on the voltage (V) and resistance (R) of the body. If the voltage is the same, but the resistance is reduced, the current passing through it will be greater.

.

The human body has a resistance value that changes according to skin type. For example, if we are wet, the resistance will be about * * 100 Ω - 1 kΩ * *. But if the skin is dry, the resistance will be as high as * * 10 kΩ - 1 MΩ * *. This means that if we are wet and barefoot, electricity can flow through the body more easily and more, so it is very vulnerable to harm. Also, if the plug or electrical device is caught in the wet or the power plug is in the flood area, there is also a chance of leakage and suction light.

.

The result depends on the amount of current passing through the body. If the current is below * * 1 mA * *, we may not feel anything, but if it is greater, it will start to feel pain, muscle contractions or spasms, and if the current is higher, it can cause cardiac arrhythmia to stop beating or skin burns.

.

Another interesting point from Ohm's law is that electricity can only pass through when there is a potential difference between two points. Notice a bird perched on a 🐦 wire. Why is the bird not sucked? Because both legs are on the same wire with the same potential, there is no potential, so there is no electricity flowing through the body, so the bird is safe.

.

The conclusion is that if the body is wet, the resistance will be significantly lower, so the current will pass through easily and in larger quantities, many times higher chance of harm. ⚡
