Best answer
Correct Answer - Option 1 : 0.045 A

Concept:

A milliampere (symbol: mA) is a submultiple of the SI base unit of electrical current, the ampere. It is defined as one-thousandth of an ampere.

Analysis:

Given:

I = 45 mA

To convert it to Ampere, we need to divide it by 1000. 

\(I = \frac{45}{1000} = 0.045~A\)
