Source sentences:
text: When the voltage is positive and greater than a minimum threshold voltage , then the diode is said to be forward biased.
text: When the voltage across the diode is negative, virtually no current flows.
text: Forward bias requires that the voltage at the anode (a) of the LED is positive with respect to the voltage at the cathode (k).
text: When the voltage across the diode is positive, a lot of current can flow once the voltage becomes large enough.
