    Undergrad Relationship between the depletion region and the band gap of a diode?

    Hi, Lately I've been reading about a lab exercise in which Planck's constant is estimated using LEDs. Every procedure I've encountered states that the energy of an emitted photon (and by extension the potential across the semiconductor's band gap) is equal to the threshold voltage multiplied by...

    Undergrad Question: Why does AC current change through a transformer?

    Thank you everyone! This makes much more sense than before. Sorry if I bored anyone with such a basic question...thanks for bearing with me!

    Undergrad Question: Why does AC current change through a transformer?

    Hello physics friends! I have a question about AC current I hope you can help me understand. So I know that putting AC through a transformer will raise or lower the voltage, but because power has to be kept constant, the current changes in the opposite direction. But according to Ohm's law...
