Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

These were good examples.
Try to do an example of too little resistance such as shorted or defective motor windings and too much resistance such as corrosion, burned contacts.
Relate the voltage drop to the excess resistance and the increase in current flow to the shorted windings.Posted by Shawn Day on 2/15/2012 8:11:43 AM Reply
