How does the transistor connect and disconnect the power at a rapid pace?
I built the same wireless electricity transmission circuit that you posted. I presented it to the professor and he really liked it but he won't give me a grade until I tell him what the transistor does. I told him that the transistor’s purpose is it to connect and disconnect the power at a rapid pace, thus creating a changing magnetic field in the inducer coil. But, he says he needs more details. Can you please help me I've searched high and low in google but I only found that answer.
