The Carnot co-efficient of performance (COP) of a domestic air conditioner compared to a household refrigerator is

A. Less

B. More

C. Same

D. Dependent on climatic conditions

Answer: Option A

Solution(By Examveda Team)

The COP of a domestic air conditioner is less than that of household refrigerator because the work input in case of domestic air conditioner is higher than refrigerator $${\bf{cop}} = \frac{{{\text{desired output}}}}{{{\text{work input}}}}.$$
