Question

question 22
the value 25 millihennys is equal to ___ hennys.
2.5
0.025
0.00000025
0.000025

Explanation:

Step1: Recall the conversion factor

We know that 1 millihenry ($mH$) is equal to $10^{-3}$ henrys ($H$). So the conversion factor from millihenrys to henrys is $1\ mH = 10^{-3}\ H$.

Step2: Convert 25 millihenrys to henrys

To convert 25 millihenrys to henrys, we multiply the number of millihenrys by the conversion factor. So we have $25\ mH\times10^{-3}\ \frac{H}{mH}$.
Calculating this, $25\times10^{-3}=25\times\frac{1}{1000}=\frac{25}{1000} = 0.025$.

Answer:

0.025 (corresponding to the option "0.025")
