What will happen if current is more than required in diode?
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
Which voltage is greater in thyristor whether forward breakover or reverse breakdown voltage?
One voltage is greater in thyristor whether forward breakover or reverse breakdown voltage. The greater of the two voltages in thyristor is forward breakover voltage.
Which voltage is greater in thyristor whether forward break over or reverse breakdown voltage?
It is stated that one of the voltage is greater in thyristor whether it be forward breakover or reverse breakdown voltage. It is also stated that the greater of the 2 voltages in thyristor is the forward breakover voltage.
Why do the voltage drops of an inductor and a lamp in a series ac circuit not equal the applied voltage?
The voltage is greater than the applied voltage, why?
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 forward current?
This is the current that flows under the application of a forward voltage. For eg. the dc forward current for an LED may be 30 mA when a forward voltage of 2.0V is applied.
How much voltage is there across a silicon diode when it is forward biased?
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
Why name of the device is UJT?
UJT means Uni Junction transistor terminals are Emitter,Base1 and Base2.UJT is also called double base diode.UJT operates when the emitter is forward biased.voltage is applied between base1 and base2.If an external voltage is applied at terminal E,no current will flow in to the emitter as long as this applied voltage is less than emitter voltage.When this applied voltage exceeds emitter voltage,current will flow into the emitter and holes get injected from emitter to base1 and are repelled by base2.This results in increase in the region between the junction and the base 1.The increase in conductivity results drop in emitter voltage and increased forward bias of the junction.so emitter current also increases.Then it exhibits a negative resistance.
Is fwd break over voltage is greater than reverse breakdown voltage i.e VboVbr?
forward breakover voltage is slightly smaller than reverse breakdown voltage
When a voltage is applied across a diode and current flows we say the diode is what?
One description would be forward biased.
What does voltage do to electrons?
It causes them to move. The greater the voltage applied, the greater the current generated (for the same resistive load), and so the more electrons move.
How do you connect an ohmmeter in series or paallel?
A: To read ohms you will use it by reading in parallel and without any external voltage applied
