Understanding Electrical Shocks
Electrical shocks happen when our bodies become part of an electrical circuit, allowing the current to flow through us. This can occur through direct contact with an electrical source, such as a wire or an appliance, or indirectly, through contact with a conductive object that has become electrified. The severity of an electrical shock depends on several factors, including the voltage and current of the electrical source, the duration of the contact, and the path the current takes through the body.
The Science Behind Electrical Shocks
To understand why electrical shocks happen, it’s essential to grasp some basic concepts of electricity. Electricity is a form of energy that is generated by the movement of charged particles, such as electrons. When these particles flow through a conductor, such as a wire, they create an electrical current. The voltage, or potential difference, is the driving force behind the current, and it is measured in volts (V). The current, measured in amperes (A), is the rate at which the charged particles flow.
Conductors and Insulators
Materials can be classified as either conductors or insulators, depending on their ability to allow the flow of electrical current. Conductors, such as metals, have a high concentration of free electrons that can move freely, allowing the current to flow. Insulators, such as plastics and wood, have a low concentration of free electrons and resist the flow of current. The human body is a relatively good conductor, as it contains a high percentage of water, which is an excellent conductor of electricity.
