Question:medium
The efficiency of a heat engine is '$\eta$' and the coefficient of performance of a refrigerator is '$\beta$'. Then
The efficiency of a heat engine is '$\eta$' and the coefficient of performance of a refrigerator is '$\beta$'. Then
Show Hint
Physics Tip : This relationship holds because both devices are limited by the same temperature differences of the reservoirs they operate between.

- $\eta = \frac{1}{\beta}$
- $\eta = \frac{1}{\beta + 1}$
- $\eta\beta = \frac{1}{2}$
- $\eta = \frac{1}{\beta - 1}$
Show Solution
The Correct Option is B
