Final answer:
Electrical energy can indeed transmit through the emptiness of space in the form of electromagnetic waves. These waves, which consist of electric and magnetic fields, do not need a medium to travel and move at the speed of light in a vacuum.
Step-by-step explanation:
The question you've asked pertains to whether electrical energy can travel through the emptiness of space. This is true. Electrical energy, when in the form of electromagnetic waves, can indeed transmit energy through a vacuum, as space is devoid of a medium. According to Essential Knowledge 6.F.2, electromagnetic waves do not require a medium and can transmit energy through both a medium and a vacuum. Electromagnetic waves consist of electric (E) and magnetic fields (B) that perpetuate each other and can travel through empty space at a speed of approximately 3 × 108 m/s, which is the speed of light (c).
When discussing the behavior of electric-field lines, it is also instructive to note that they cannot cross each other; hence, no two electric-field lines can exist at the same point in space. Remember also, that lightning can travel through materials that are typically insulators, such as wood, in cases where the electric potential is very high.
