What is LED Forward Voltage?
The forward voltage of an LED is the voltage that must be applied across the leads of an LED, anode to cathode, in order for the LED to function and turn on.
What is meant by cut in voltage in diode?
Cut in voltage (Knee voltage): The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage.
What happens to an LED When the voltage is to high?
when a LED is subjected to a high voltage it will heat up and burn the internal junction, which will leave the LED open circuit.
What is Cut-off voltage in fet?
fet is a voltage controlled device...cut off voltage in fet refers to that voltage of the gate - source junction at which the current flow through channel is zero
What is knee voltage and breakdown voltage?
Knee voltage (cut in voltage) :-The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage Breakdown voltage :-It is the minimum reverse voltage at which the P-N Junction can conduct without damage to the current

Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
Why does a Led have a 470 resistor connected to the LED?
A: That resistor is there to limit the current to the LED it can be any value if the voltage is decreased or increased or no resistor if the voltage across the led is equal to the forward voltage drop.
Definition of cut in voltage of diode in electronics?
zener cut in voltage
Give the operating voltage of LED?
A; a LED can have a voltage of 1.8v to 5 or higher voltage whites and red are usually in the low voltage while green and blue are int he range of higher voltage
What is meant by cut in voltage?
Cut-in voltage is the value of voltage at which appreciable current begins to flow when a pn junction is forward biased.
What is the value of the voltage the led light needs?
There's no set voltage that'll run ALL led's, it'd depend on the particular led.
The voltage drop across led is?
The voltage drop across an LED varies, but is typically around 2 volts.
What happens to an LED When the voltage is to high?
when a LED is subjected to a high voltage it will heat up and burn the internal junction, which will leave the LED open circuit.
What is Cut-off voltage in fet?
fet is a voltage controlled device...cut off voltage in fet refers to that voltage of the gate - source junction at which the current flow through channel is zero
Fet in cut off voltage?
fet is a voltage controlled device...cut off voltage in fet refers to that voltage of the gate - source junction at which the current flow through channel is zero
