Frayed wires, worn insulation, or loose electrical connections can cause:
-
Electricity to leak out
-
Short circuits, electric shock or fire
-
Dirt in the wires
-
Spontaneous combustion
Correct Answer
A. Short circuits, electric shock or fireExplanation
Frayed wires, worn insulation, or loose electrical connections can cause short circuits, electric shock or fire. When wires become frayed or insulation becomes worn, it can expose the electrical current, leading to a short circuit. A short circuit occurs when the current takes a path of least resistance, bypassing the intended circuit. This can cause an excessive flow of electricity, leading to overheating, sparks, and potentially a fire. Loose electrical connections can also cause a similar issue, as they can create resistance and generate heat, increasing the risk of fire or electric shock.Rate this question:

When loosening a tight bolt or nut, which one of the following is appropriate action?
-
Pull the wrench
-
Push the wrench
-
Stand on the wrench
-
Get a smaller wrench
Correct Answer
A. Pull the wrenchExplanation
When loosening a tight bolt or nut, the appropriate action is to pull the wrench. This is because pulling the wrench in the opposite direction of the tightening motion applies a counterforce, allowing the bolt or nut to loosen. Pushing the wrench or standing on it would not provide the necessary force to loosen the tight bolt or nut. Getting a smaller wrench may not be effective if the current wrench is already the appropriate size for the bolt or nut.Rate this question:
