The learner will understand the operation of motor control circuits used to start and stop three-phase motors.
Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.
Learners view the steps to find the complex conjugate of a number in polar form using a TI-86 calculator.
You'll learn to round decimal numbers to the given place value.
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
