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.

Students view the steps for subtracting complex numbers in Excel.

In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
