Allow electricity to only flow in one direction Allow electrons to flow one way only until reverse breakdown occurs then current may flow in both direction There are many uses for diodes in a...
They only allow current to flow in one direction.
A: It limits the voltage to a manageable level defined by the diode charactheristics
A passive element is an element of the electrical circuit that does not create power, like a capacitor, an inductance, a resistor or a memristor.
