Excellent presentation it is good at reinforcing the subject and can help supplement reading items great for practice.
it's very nice.one can easily understand the concepts by animation.
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. 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.
In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.
You'll practice solving problems using the rule for multiplying powers with the same base.
