What two factors affect the severity of an electric shock?

The severity of electrical shock or electrocution injuries usually depends on three things: (1) the path the current travels in and through the body, (2) the amount of voltage (high-voltage versus low-voltage), and (3) the type of current (alternating current or AC versus direct current or DC).

What are the two causes of an electric shock accidents?

Causes of electric shock

  • Faulty appliances.
  • Damaged or frayed cords or extension leads.
  • Electrical appliances coming in contact with water.
  • Incorrect or deteriorated household wiring.
  • Downed powerlines.
  • Lightning strike.

What does electric shock depend on?

The effects of electric shock on the human body depend on the current that flows—the amperage—rather than on the force of the current, or voltage. The electrical resistance of the human body is variable and may in fact alter considerably during the passage of an electric shock.

What causes electric shock voltage or current?

Originally Answered: What causes an electric shock current or voltage? Voltage is the one which drives the electrons to flow in a body (conductor). as we are a conducting material,the voltage causes the electrons in our body to flow and thus produces the current to flow throughout the body. so you get current shock.

What are the 3 possible factors causing electrical accidents?

Most electrical accidents result from one of the following three factors: Unsafe equipment or installation. Unsafe environment or. Unsafe work practices.

Is the severity of an electric shock depends more on the voltage when compared to the current?

Severity. The severity of injury from exposure to electricity depends on two factors: the level of electrical current (amperage) and the duration the current passing through the body. … The higher the voltage and lower the resistance, the greater the current.

Does the severity of an electric shock increase or decrease with each of the following changes?

As the current flowing through the human body is less, the severity of shock decreases. Thus, the severity of an electric shock decreases with a decrease in the source voltage. … An increase in the body current flow increases the severity of electric shock.

What determines the severity of injury in arc flash?

Three factors determine the severity of an arc flash injury: proximity to the hazard, temperature and duration for the circuit to break. … An arc can generate heat as high as 35,000°F and a significant pressure wave blast. This can result in severe burns, destroying skin and tissue.

What are the effects of shock?

The symptoms of shock include cold and sweaty skin that may be pale or gray, weak but rapid pulse, irritability, thirst, irregular breathing, dizziness, profuse sweating, fatigue, dilated pupils, lackluster eyes, anxiety, confusion, nausea, and reduced urine flow. If untreated, shock is usually fatal.

What is the effect of electric shock on human body?

A shock can affect the nervous system

When nerves are affected by an electric shock, the consequences include pain, tingling, numbness, weakness or difficulty moving a limb. These effects may clear up with time or be permanent. Electric injury can also affect the central nervous system.

What causes electric shock feeling in hands?

Carpal tunnel syndrome symptoms usually affect the thumb and index (pointer) finger, and sometimes also the middle and/or ring fingers. The sensation may feel like a pulse of electric shock, and the pain may reach and radiate into the arms.
