Question
How many milliamperes is 1.5 amperes?
Answer Options
- A) 15 milliamperes
- B) 150 milliamperes
- C) 1500 milliamperes
- D) 15,000 milliamperes
Correct Answer: C
Explanation
This is a unit conversion problem using the standard metric prefixes. The prefix ‘milli-’ (\text{m}) means one one-thousandth (\text{1/1000}). Therefore, one ampere (\text{A}) is equal to 1,000 milliamperes (\text{mA}).
To convert 1.5 amperes to milliamperes, you multiply: 1.5\text{ A} \times 1000\text{ mA/A} = 1500\text{ mA}. This conversion is necessary when measuring or describing small currents common in low-power electronics.
