How many volts does it take for the human body to feel a static discharge?

The sensation of static electricity, often described as a "static shock," typically occurs when the voltage reaches around 3500 volts. At this level, the electrical discharge is sufficient for the human nerves to detect the sensation. The threshold for feeling a static discharge can vary among individuals but generally falls around this range. It’s common to experience this sensation when touching objects that have accumulated static electricity, particularly after walking on carpets or during dry weather conditions.

The other voltage levels presented are either above or below this threshold, meaning they do not align with the common experience of feeling static electricity. Options like 1000 volts and 2500 volts are generally considered too low to elicit a strong sensation in most individuals, while 5000 volts is higher than the typical threshold needed for perceivable static discharges. Therefore, the most accurate answer reflecting the general human experience with static electricity is indeed 3500 volts.
