The relation between efficiency \((\eta)\) of Carnot engine and coefficient of performance ( \(\eta_1\) ) of refrigerator is
- A \(\eta=\frac{1}{1+\eta_1}\)
- B \(\eta=\frac{1}{1-\eta_1}\)
- C \(\eta=\frac{\eta_1}{1-\eta_1}\)
- D \(\eta=\frac{1+\eta_1}{\eta_1}\)
Answer & Solution
Correct Answer
(A) \(\eta=\frac{1}{1+\eta_1}\)
Step-by-step Solution
Detailed explanation
\(\eta_1 = \frac{Q_C}{Q_H - Q_C}\) \(\eta_1 = \frac{Q_C/Q_H}{1 - Q_C/Q_H}\)
