How many amperes are equal to 200 milliamperes?

To convert milliamperes to amperes, you need to understand the relationship between these two units. One ampere (A) is equal to 1,000 milliamperes (mA). Therefore, to convert milliamperes to amperes, you divide the number of milliamperes by 1,000.

In this case, 200 milliamperes is converted to amperes by taking 200 and dividing it by 1,000:

200 mA ÷ 1,000 = 0.2 A.

This calculation clearly shows that 200 milliamperes is equivalent to 0.2 amperes, making it the correct choice. Understanding this conversion is fundamental in electrical work, as it allows for accurate readings and calculations when dealing with electrical currents in circuits.
