Introduction
The harm caused by electric current to the human body is generally related to factors such as the magnitude of the current, voltage level, and current frequency. In addition, the purpose for which the current is used and the method of its application can also have corresponding effects on the extent of injury. In cases of electric shock, prompt medical attention is essential; it must be taken seriously to prevent irreversible damage to the human body.
The harm caused by electric current to the human body is generally related to factors such as the magnitude of the current, voltage level, and current frequency.
1. Current Magnitude
If the current is not very large, the physiological response after contact is usually minor and generally not harmful. However, if the current is substantial, significant physiological reactions may occur upon contact, such as pain.
2. Voltage Level
Higher voltage levels tend to cause greater harm to the human body and may result in severe injuries. Conversely, lower voltages typically lead to relatively less damage upon contact.
3. Current Frequency
The lower the current frequency, the smaller the potential harm to the human body. As the frequency increases, the risk of injury also increases, potentially even endangering life.
In addition, the extent of injury is also related to the body's electrical resistance. After an electric shock, the victim must be promptly taken to a hospital. This should be taken seriously to prevent irreversible damage caused by electric current.
