The efficiency of a machine is the ratio between the output power and the power in input:
in our problem, the output power is 3760 W while the input power is 4000 W, so the efficiency is
So the efficiency of the machine is 94%.
in our problem, the output power is 3760 W while the input power is 4000 W, so the efficiency is

Answer:
30 C
Explanation:
Given:
Current flowing in the circuit (I) = 50 A
Start-up time (t) = 0.60 s
Now, we know that, charge drawn in through a cross sectional area of the circuit is given as:
Where, 'q' is the amount of charge drawn, 'I' is the current and 't' is the start-up time.
Now, plug in 50 A for 'I', 0.60 s for 't' and solve for 'q'. This gives,
Therefore, the amount of charge drawn in the circuit at the start-up of the compressor of an air conditioner is 30 C.
