Question

What causes physical pain and/or damage to the body when electrical contact is made?

Answer 1

When electrical contact is made with the body, the severity of the physical pain and/or damage depends on the amount of current, the path taken by the current, the duration of the shock, and the frequency of the current.

Step-by-step explanation:

When electrical contact is made with the body, it can cause physical pain and/or damage due to the effects of electric shock. The severity of the effects depends on several factors:

1. The amount of current: The higher the current, the more severe the effects.
2. The path taken by the current: The current prefers to flow through paths with lower resistance, such as those that provide a direct path to the ground.
3. The duration of the shock: The longer the duration, the more damage it can cause.
4. The frequency of the current: For direct current (DC), the frequency is 0, but for alternating current (AC), the higher the frequency, the more likely it is to cause harm.
