Is zener diode an ideal current source?
A: An ideal current source can be defined as a short with immense current capabilities A zener has no such capabilities
Can TVs diode can be connected in series to increase the surge current?
No. By Kirchoff's Current Law, components in series all see the same current.
How does a bridge rectifier operates?
A: must assume an AC source of greater amplitude of .7volts then when the source reaches .7 volts a diode will conduct if the positive voltage is at the anode then it will proceed to go trough the load and return the current to the diode connected to the negative of the source. That basically finishes one half of the cycle when the AC reverses polarity then the same process of current flow will finish the complete cycle. while different series diode conduct one way the other will not conduct because of reverse biasing. but the load will conduct current one way for both cycles
What are the sources of reverse current in a diode?
doping concentration,temperature are the major source of reverse current
Why full eave rectifier rectifies negative half cycle?
the rectifier is Mainly used to convert the Ac current into DC current .In rectifier there are two diodes or (4 Diode In full wave bridge rectifier )are use is to conduct the current one is connected in forward bias(i.eD1) and the other is connected in reveres bias(i.eD2). As we know that the diode is conduct the current throw it When it is connected in forward bias . now when the voltage is applied to the circuit the the AC Current is start to flow throw circuit and in Positive half cycle of Ac current the Diode is Allow the current Pass throw it and during the Negative half cycle the Diode D2 is allow the current pass throw it and in these way the rectifier rectifies positive As Well As the negative half cycle
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What is leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What will happens if zener diode and resistance are connected in parallel?
If diode is connected in series then current will flow only in one direction. ie. Current flow occurs only when diode is forward biased. ANSWER: It depends are the diodes are connected in series if they are back to back no current will flow if connected in the forward conduction mode then they will conduct.
What is unbiased diode?
when we do not apply any source of energy or electricity than a Dodie is said to be un biased Dodie.
What is the source of diode in reverse biased condition?
The anod terminal of diode is connected with negative and cathod is connected to positive
Is zener diode an ideal current source?
A: An ideal current source can be defined as a short with immense current capabilities A zener has no such capabilities
What is difference between cell and diode?
A "cell" (word for part of a battery) is a source of current flow.A diode is a device that restricts current flow to one direction.
If diode is connected to two voltage sourceone in forward biased other biased diode in rewrse what will be net effect of two source on diode?
If a diode is connected with two voltage sources for ex: One is 5V in F.B and The other is 3V in R.B then the Effective voltage will be equal to 2V F.B. So, The diode conducts.
Can TVs diode can be connected in series to increase the surge current?
No. By Kirchoff's Current Law, components in series all see the same current.

What is blocking diode?
any diode if connected to where the anode is tie to a negative potential will block that voltage. Up to the limit of the breakdown potential of the diode whereby avalanche current will destroy the diode unless current limited
What are the sources of reverse current in a diode?
doping concentration,temperature are the major source of reverse current
