Question: 1 / 435

How is 1 ampere mathematically represented in terms of microamperes?

1,000 microamperes

100,000 microamperes

1 million microamperes

One ampere is mathematically represented as 1 million microamperes because the prefix "micro-" denotes a factor of one-millionth (1/1,000,000). Therefore, when converting amperes to microamperes, you multiply by 1 million.

The relationship can be understood as follows:

1 ampere = 1,000,000 microamperes.

So, when considering how many microamperes are in an ampere, it is clear that multiplying by this conversion factor results in the correct answer being 1 million microamperes.
