(‘close-up view’ of a ‘silicon di-ode’)
(the ‘anode’ is at the ‘right side’)
(the ‘cathode’ is at the ‘left side’)
(where it is marked with a ‘black band’)
(the ‘square silicon crystal’ can be seen between the 2 ‘leads’)

*LED – “light-emitting diode”*
.
-a ‘diode’ is a 2-terminal electronic component with asymmetric ‘conductance’-
.
(it has ‘low’ (ideally zero) ‘resistance’ (to ‘current’) in 1 direction…)
.
(…and ‘high’ (ideally infinite) ‘resistance’ in the other)
