Electrical Components which are not properly grounded may create electrical shocks:

Electrical current pass through body only when there is a potential difference:

___ is a unit used to measure the opposition to the flow of electrical current in a circuit

The connection to the ground is made through properly buried

A person can receive electrical shock even when he is not in contact with ground

Unit of electrical current:

The severity of the injury caused by the electric shock is independent of the magnitude of the electrical current pass into the body but depends on the voltage magnitude

Severity of electric shock depends on:

Current of magnitude 1 milli amp flowing through the body can lead to:

50 to 150 milli amperes current flowing through human body results in respiratory failure and severe muscle contractions:

10 amperes of electrical current is sufficient to cause cardiac arrest

During electrical shock, electric current always flows through chest (heart and lungs)

Low voltage electrical shocks are more danger and fatal than high voltage electrical shocks

Wet skin will have resistance of about ____

Severity of electrical shock will be higher in which of the following

Person will less muscle tissue will have severe shock impact at much lower current levels

Residential wiring may not comply with NEC but shall be comply with OSHA

Current that pass through the heart and nervous system are more fatal shocks

Current in which circuit will be divided among different branches:

High voltage shocks cause electrical burns

Electrical Burn may result from the heat of the fire

Severity of Arc burns depends on the color of the skin and area of skin exposed

Arcing during an arc blast gives off which of the following:

Temperatures as high as ____ may be reached in arc blasts

In arc blasts, high ampere current travel through the air between the conductors

Arc blasts can occur in both at low voltage and high voltage in a system

During arc blast explosive molten metal of the equipment will be released
