The diode is a unidirectional device it allows current to pass through it only when it is forward biased and does not allow when reverse biased
when ac signal is supplied in the positive half cycle of the ac wave signal the diode will b in forward biase n in the negative half cycle it is in reverse bias .Hence it allows only the positive half cycle current to flow through it
the resultant wave form will b only in one direction ,i.e,dc signal with ripples.
only half of the wave is rectified hence it acts as a half wave rectifier
What else can I help you with?
Can a diode act as a source of emf?
NO
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
Is diode an active device?
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
Which is better as a switch diode or transistor?
Basically a diode is a combinstion of pN junction but the transistor is made with three terminals EMITTER,, BASE ,, JUNCTION.. and diode is just a combination of positive and negative terminal . diode and transistors are both used as a switch .. but a transistor is more widly udes than a diode. and diode has also very important in electronics DIGITAL SYSTEM to make the screen's ..and transistors are used in amplifiers the group of transistors make an amplifier . and we use a diode in seven segment display ....diode is small and carry less current due to its small size but transistor get large current. A2 A diode has two connections. It allows current to flow in one direction and not in the other. They are used for rectification in power supplies, detection of AM radio, blocking of current etc. A Transistor has three connections. Current is controlled between the emitter and collector, by a small current on the base. They are used as switches, amplifiers and regulators.
How do you xxplain the zener shunt regulator?
zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator
Can clipper act as a half wave rectifier?
A clipper can act as a half wave rectifier but it might be a little hard.
Does the commutator of a DC machine act as a half-wave rectifier?
No.It act as fullwave rectifier
Four diode bridge rectifier if one diode is faulty?
if one diode is open circuited(a break in the circuit): it will act as a half wave rectifier .only +ve or -ve 1/2 cycles available at o/p. if one diode is short(more probable case due to burn out). this place a short across source for one half cycle,may destroy circuit.
Why diode act as an insulator?
Diode is a semiconductor material. so it act as insulator also.
Can a diode act as a source of emf?
NO
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
Is diode an active device?
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
Can a zener diode act as a surge protector?
Yes, and it's quite common to see one used as such. Whenever the voltage exceeds the rating of the diode, the diode will conduct and usually short circuit the excess voltage to ground. It's been commonly called a `crowbar circuit' and using the diode, it can be configured in several different configurations, depending on your application. A zener designed for such applications is often called a TVSS or avalanche diode. These feature lower incremental resistance, faster response times, lower leakage currents, and smaller capacitance as compared to conventional zener diodes. Downside of a zener diode is its tiny power handling abilities. Similar function is also performed using a Silicon Controlled Rectifier (SCR) for DC or a thyristor (triac) for AC.
When a 3.3 V zener diode is parallel with a 7 V zener diode what is the break down voltage?
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
What is the function of zener dioed?
The function of a zener diode is for it to act as a voltage regulator in the breakdown region.
What is the function of a diode in a circuit?
The most common function of a diode is to allow an electric current to pass in one direction (called the forward biased condition) and to block the current in the opposite direction (the reverse biased condition).
Can a wave act like a particle?
Yes
