Electrical energy can primarily produce which of the following?

Electrical energy has the ability to produce heat through a process known as Joule heating or resistive heating. When electrical current flows through a conductor or resistor, the electrical energy is converted into thermal energy due to the resistance the material offers to the flow of electricity. This is a fundamental principle used in many everyday appliances, such as toasters and electric heaters, where the primary function is to generate heat.

While electrical energy can also produce light, motion, and sound, the question specifically asks for what it can primarily produce. Heat generation tends to be the most common byproduct in electrical systems, making it a primary focus in many electrical applications, especially in the context of safety and efficiency.

Light can be produced through electric currents in devices like light bulbs and LEDs, motion is the result of motors converting electrical energy to mechanical energy, and sound can be produced in devices like speakers. However, heat is generally a more prevalent and significant effect of electrical energy in a wider range of applications, thus underscoring why this aspect is considered primary.
