This physics video tutorial provides a basic introduction into transformers. It explains how to calculate the voltage, current, and power in the primary coil and the secondary coil given the number of primary turns and secondary turns. This video also explains how to determine the efficiency of a transformer and how to determine if a transformer is a step up transformer or a step down transformer. This video contains plenty of examples and practice problems.
