In the circuit above, the function of resistor R and diode D are
to limit the current and to protect LED against over voltage
to limit the voltage and to protect LED against over current
to limit the current and protect LED against reverse breakdown voltage.
none of the above.
Correct answer is C
Resistance limits current and diode is reverse connected and therefore protects LED against reverse breakdown.
