Diodes
● A diode is an example of a semi­conductor component ● The function of a diode is to control the direction of electricity ● Diodes act like a valve, where they only allow the electrons to flow in one direction through them. ● Think of a diode as a one­way street for electricity. ● Every diode has two terminals (ends) that are polarized. One is positive, one is negative. ● The positive end of a diode is called the anode, and the negative end is called the cathode. ● There are several kinds of diodes ● An LED is an example of a diode (light­emitting­diode) ● A photocell is also a diode
