7.Choose the correct answer If the pulse duration decreases at a constant frequency of the pulse current, then the filling factor __ decreases sharply decreases increases doesn't change

## Step 1<br />The filling factor is a measure of the time that the pulse is on during one cycle. It is calculated by duration by the pulse period.<br /><br />### **Filling Factor = \(\frac{Pulse Duration}{Pulse Period}\)**<br /><br />## Step 2<br />If the pulse duration decreases while the frequency (and therefore the pulse period) remains constant, the filling factor will decrease.
