Swinburne test is conducted under which load condition:
- Full load
- Half load
- No load
- Any of the above
Correct answer: 3. No load
Explanation:
The Swinburne test is a method used to determine the efficiency of a DC machine. It involves running the machine under no-load conditions, typically at rated voltage but with no mechanical load applied to the shaft. During the test, both the input power (electrical power supplied to the machine) and the output power (mechanical power developed by the machine) are measured.
So, the correct answer to the multiple-choice question would be:
No load
