Final answer:
The use of power strips as extension cords for technology equipment is not specifically recommended by electrical codes, and this statement is false. Option B is correct.
Step-by-step explanation:
The statement 'The electrical code in most areas recommends the use of power strips as electrical extension cords for technology equipment' is false. Power strips often come with built-in surge protectors, which can provide some protection for electronics. However, they are not necessarily recommended over other extension solutions, and one needs to adhere to specific guidelines when using them to prevent overloading and possible fire hazards.
Regarding the other statements presented:
The high-voltage wires connected to tall metal-frame towers are typically held aloft by insulating connectors, but they are not usually wrapped in an insulating material. This statement is false.
It is true that one should not place credit cards with magnetic strips near permanent magnets because it can demagnetize the strip and ruin the card. This statement is true.
In a circuit diagram, it is false to assume that voltage is the same at every point in a given wire due to potential voltage drops across components in the circuit.
The electric-field lines from a positive point charge do indeed spread out radially and point outward. This statement is true.
If you drop a bar magnet through a copper tube, it does induce an electric current in the tube as it falls, due to Lenz's law, and this statement is true.
If the voltage drop across an extension cord is significant, it can reduce the voltage available for an appliance, which in turn may decrease the appliance's power output and hamper its functioning. Hence, this explanation is true.
