The following is an example of work that may be performed by a person who is not an electrician at work place:
-
Connecting of an extension cord using a standard junction box
-
Removal of grounding pin from appliance cord plug
-
Use of proper extension cord to power an appliance for a short time
-
None of the above
Correct Answer
A. None of the aboveExplanation
All of the given tasks involve electrical work that should only be performed by a qualified electrician. Connecting an extension cord using a standard junction box requires knowledge of electrical wiring and safety precautions. Removing the grounding pin from an appliance cord plug is dangerous and can lead to electrical shock hazards. Using a proper extension cord to power an appliance for a short time also requires understanding of electrical specifications and safety guidelines. Therefore, none of the above tasks should be performed by a person who is not an electrician.Rate this question:

Electrical current can flow through human body.
-
True
-
False
-
Can not say
-
None of the above
Correct Answer
A. TrueExplanation
Electrical current can flow through the human body because the human body contains water and electrolytes, which can conduct electricity. When a person comes into contact with an electrical source, such as a live wire, the current can pass through the body, potentially causing injury or even death. This is why it is important to be cautious around electricity and take necessary safety precautions to avoid electrical accidents.Rate this question:

Which of the following are classified as unsafe acts?
-
Altering a 3-prong plug to fit a 2-prong outlet
-
Using a GFCI
-
Working too close to overhead power lines
-
A and C
-
All of the above
Correct Answer
A. A and CExplanation
Altering a 3-prong plug to fit a 2-prong outlet and working too close to overhead power lines are classified as unsafe acts. Altering a plug can lead to electrical hazards and increase the risk of electric shock or fire. Working too close to overhead power lines can result in electrocution if proper safety precautions are not followed. Using a GFCI (Ground Fault Circuit Interrupter) is actually a safety measure that helps protect against electrical shocks, so it is not classified as an unsafe act.Rate this question:

Electric cords connected to equipment may be used for raising or lowering the equipment.
-
True
-
False
-
Can not be determined
-
None of the above
Correct Answer
A. FalseExplanation
Electric cords are used for transmitting electricity from a power source to equipment, not for raising or lowering the equipment. The function of electric cords is to provide a power supply, not to physically manipulate the position of the equipment. Therefore, the statement that electric cords connected to equipment may be used for raising or lowering the equipment is false.Rate this question:

Conductive articles of jewelry and clothing can be worn around exposed energized parts.
-
True
-
False
-
Depends upon the weather
-
None of the above
Correct Answer
A. FalseExplanation
Conductive articles of jewelry and clothing should not be worn around exposed energized parts because they can create a pathway for electrical current to flow through the body, which can lead to electric shock or other serious injuries. It is important to avoid wearing any conductive materials, such as metal, near energized parts to ensure personal safety.Rate this question:

Extension cords must have the following:
-
UL Listing
-
Three prongs
-
A fuse
-
All of the above
Correct Answer
A. All of the aboveExplanation
Extension cords must have UL Listing, three prongs, and a fuse. UL Listing ensures that the extension cord meets safety standards and has been tested for potential hazards. Three prongs indicate that the cord is grounded and can provide a safe electrical connection. A fuse acts as a protective device, preventing overloading and potential fires. Therefore, all of the mentioned requirements are necessary for a safe and reliable extension cord.Rate this question:

At same voltage, DC is more dangerous than AC.
-
True
-
False
-
Can not be determined
-
None of the above
Correct Answer
A. FalseExplanation
The given statement is false. AC (alternating current) is considered to be more dangerous than DC (direct current) at the same voltage. AC has the ability to cause muscle contractions, making it more likely to freeze a person's grip on a live conductor, making it difficult to let go. Additionally, AC can cause the heart to fibrillate, which can be fatal. On the other hand, DC is less likely to cause muscle contractions and is easier to let go of, making it generally safer than AC.Rate this question:

Non-conductive head protection should be worn whenever there is a danger of head injury from electric shock.
-
True
-
False
-
Not necessary
-
None of the above
Correct Answer
A. TrueExplanation
Non-conductive head protection should be worn whenever there is a danger of head injury from electric shock because it helps to prevent the flow of electric current through the head, reducing the risk of electrical burns or other injuries. Conductive materials, such as metal, can conduct electricity and increase the severity of an electric shock. Therefore, wearing non-conductive head protection is necessary to protect against electric shock-related head injuries.Rate this question:

Severity of an electric shock depends on:
-
Path of current through the body
-
Amount of current flowing through the body
-
Length of time the body is in the circuit
-
All the above
Correct Answer
A. All the aboveExplanation
The severity of an electric shock depends on multiple factors, including the path of the current through the body, the amount of current flowing through the body, and the length of time the body is in the circuit. All of these factors play a role in determining the extent of injury or harm caused by an electric shock.Rate this question:
