What is the inductance of a 20 millihenry inductor in series with a 50 millihenry inductor?

0.07 millihenrys
14.3 millihenrys
70 millihenrys
1000 millihenrys

The correct answer is: 70 millihenrys

When inductors are connected in series, the total inductance is the sum of the individual inductances. In this case, you have a 20 millihenry inductor and a 50 millihenry inductor. To find the total inductance, you simply add these values together: Total Inductance = Inductance1 + Inductance2 Total Inductance = 20 millihenries + 50 millihenries Total Inductance = 70 millihenries This calculation shows that when inductors are connected in series, their inductances add directly, leading to a total inductance of 70 millihenries. Understanding this fundamental principle of inductances in series is crucial for circuit analysis and design in radio applications.
