hatásfokuk

Hatásfokuk is a Hungarian term formed from hatásfok (efficiency, effectiveness) with the third-person plural possessive suffix -uk. It denotes the efficiency or performance level belonging to a group of subjects, such as multiple machines, devices, or processes. In English, it would translate roughly as “their efficiency.” The form is used when describing the collective efficiency of several items or systems.

Hatásfok itself is defined as the ratio of useful output to total input in a system. It is a dimensionless quantity, often expressed as a percentage, and is a central concept in engineering, physics, and energy discussions. For example, if three devices together consume 1000 units of energy and produce 800 units of useful work, their hatásfokuk would be 0.8 or 80 percent. The concept applies across thermal, electrical, mechanical, and chemical domains; higher hatásfokuk indicates better overall performance, typically achieved through design improvements, control strategies, or efficiency-enhancing technologies. Real-world hatásfok is often below a theoretical maximum set by physical laws, such as the second law of thermodynamics.

Etymology-wise, hatásfok combines hatás (effect) and fok (degree, level). The suffix -uk marks possession by a plural subject, yielding a single noun that refers to the group’s efficiency. Related terms include energiahatékonyság (energy efficiency) and teljesítmény (performance). In usage, hatásfokuk highlights the collective efficiency of multiple items rather than the singular efficiency of one element.
