Question

Assertion (A): The power consumption of a centrifuge with direct drive electric motor connection is lower.
Reason (R): The losses of belt or gear drive are minimized.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct and (R) is NOT the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Direct drive: lower power consumption.
Minimizes losses compared to belt/gear drives.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Centrifuge drives can have different connections.
Direct drive and belt/gear drives have different efficiencies.

Step 2: Key Formula or Approach:
No specific formula.
Need to understand centrifuge drives.

Step 3: Detailed Explanation:
Assertion A: Direct drive motor has lower power consumption - correct.
Reason R: Losses of belt/gear drive are minimized - correct.
The reason explains why direct drive has lower power consumption.
Thus, both A and R are correct, and R explains A.

Step 4: Final Answer:
Both (A) and (R) are correct and (R) is the correct explanation of (A).
Hence, the correct option is (A).
