A human cannot feel a static discharge as high as _____ volts. A. 200 B. 2000 C. 10000 D. 50000 E. 50

200
2000
10000
50000 E. 50

The correct answer is: A. 200 volts.

A human cannot feel a static discharge as high as 200 volts. The amount of voltage required to produce a perceptible shock varies from person to person, but it is generally accepted that 200 volts is the threshold at which most people will feel a shock.

The amount of current that flows through the body during a static discharge is also important. The higher the current, the more painful the shock will be. The current that flows through the body depends on the resistance of the skin and the path of the current through the body. The skin is a good insulator, so it takes a relatively high voltage to create a current that will flow through the body. The path of the current also affects the amount of pain that is felt. A current that flows through the heart or brain is more likely to be fatal than a current that flows through a muscle.

The duration of the static discharge also affects the amount of pain that is felt. A longer discharge will cause more pain than a shorter discharge.

The following options are incorrect:

  • B. 2000 volts: A static discharge of 2000 volts is likely to be painful.
  • C. 10000 volts: A static discharge of 10000 volts is likely to be very painful and may cause injury.
  • D. 50000 volts: A static discharge of 50000 volts is likely to be extremely painful and may cause serious injury or death.
  • E. 50 volts: A static discharge of 50 volts is usually not painful, but it can be if the person is very sensitive or if the discharge is concentrated in a small area.
