Wonderful Wizard of Electronics

Follow Dorothy's new journey into the world of circuitry, where she meets a curious trio of electronic components: a FET transistor longing to connect, a not-so-bright LED yearning to shine, and a resistor who just wants to feel warmth inside. Through this imaginative adaptation of L. Frank Baum's classic tale, young readers will discover the magical realm of electric fields and circuits, and how individual devices work together for a purpose larger than themselves. As Dorothy and her companions travel along the Circuit Board Road, they discover that the power they sought from the Wizard had been flowing through them all along-they just needed to work together.

Includes a detailed educational Appendix following the development of field effect transistor, through logic gates, to integrated circuits and billion transistor GPU's for AI.
