This learning object is a really straight forward way of teaching the phase and line voltage relationships.
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.
