Problem:
Given:
L1 = 200mH
L2 = 800 mH
L3 = 1.2H
Find:

LT

Procedure:  
1. Set up the appropriate equation

LT = L1 + L2 + L3

 
2. Substitute the known values

LT = 200mH + 800mH + 1000mH

 
All terms must be expressed in the same units.
3. Do  the math

200mH + 800mH + 1000mH = 2000mH

 
4. Normalize the result for engineering notation

2000mH = 2H

 
Solution

LT = 2H
