A student measures a current as 0.05 A. Which of the following correctly expresses this result?
Correct answer: A. 50 mA
- A. 50 mA
- B. 50 µA
- C. 500 mA
- D. 500 µA
Explanation
The current of 0.05 A can be expressed as 50 mA because 'milli' means one thousandth, making 0.05 A equivalent to 50 milliamperes. Option A is correct. Option B (50 µA) and Option D (500 µA) are incorrect because microamperes are much smaller than milliamperes. Option C (500 mA) is incorrect because it represents a larger current than 0.05 A.

About Physical Quantities and Units
Physical quantities combine a numerical value with a unit, and are expressed using SI base units or derived units such as newtons, joules and pascals. The topic covers prefixes, unit conversion, dimensional analysis, significant figures and measurement uncertainty, while distinguishing scalar quantities from vectors where direction matters.
