How can 0.000001 Amp be expressed?

The expression of 0.000001 Amp can be converted into milliAmperes (mA), where 1 milliAmpere is equal to 0.001 Amps. To convert 0.000001 Amp into milliAmperes, you can use the following relationship:

1 Amp = 1000 mA

Therefore, to convert 0.000001 Amp into milliAmperes, you multiply by 1000:

0.000001 Amp × 1000 = 0.001 mA.

This shows that 0.000001 Amp is indeed equal to 0.001 milliAmperes. This makes the statement that 0.000001 Amp is equal to 1.0 mA incorrect, as 1.0 mA is substantially larger than 0.000001 Amp.

The other options also present values that do not correspond to 0.000001 Amp when calculated. Given that 1.0 mA is equivalent to 0.001 Amp, it is evident that 0.000001 Amp cannot equal 1.0 mA and makes option A the incorrect choice.

Thus, the appropriate conversion leads to the conclusion that 0.000001 Amp expressed in
