Question

What happens if you put a diode in backwards?

Answer 1

1. A diode is composed of an N-type semiconductor joined with a P-type semiconductor.
2. The N-type semiconductor is the negative end of the diode and is called the "cathode".
3. The P-type semiconductor is the positive end of the diode, and is called the "anode".
4. The current flowing through the diode depends on how the diode is connected.
5. 
6. If the positive side of a voltage source is connected to the positive end of the diode (the anode), and the negative side is connected to the negative end of the diode (the cathode), the diode will conduct current.
7. If the diode is reversed, the current is blocked (up to a limit).
