Plzz explain briefly
EX-2
There are
two LEDS that can
be used as a polar ity det'.
Apply a +ve source voltage
and a green Light results.
GREEN Negative Supplies result
in a RED Light. Packages
of such combinations are
RED
Commercially available.
Find the resistor R to ensure a
CUrrent of 20 mA through the "ON
diode · Both diodes havě a reverse
breakdown voutage of 3V and an
average
turn on voltage of 2v.
