What symbol represents the percent efficiency of an AC induction motor?

• A. Lambda: λ
• B. Omega: ω
• C. The Greek letter Eta: η
• D. Alpha: α

Answer: (C)

The symbol that represents the percent efficiency of an AC induction motor is the Greek letter Eta (η). In the context of electrical and mechanical systems, η is widely used to denote efficiency, indicating how effectively the motor converts electrical input into mechanical output. The value of efficiency is usually expressed as a percentage, which is essential for evaluating the performance of motors in various applications. Understanding this symbol is crucial for calculations involving energy consumption and performance in AC induction motors. In contrast, Lambda (λ) is often associated with wavelength in physics, Omega (ω) typically represents angular frequency or angular velocity, and Alpha (α) may refer to various parameters in different contexts, none of which represent efficiency. Therefore, η stands out as the standard symbol for efficiency in engineering and physics.
