What is the difference between series and parallel diodes?
Connecting diodes in series:Connecting diodes in series will increase the forward voltage of the resultant diode.Connecting diodes in series will cause an open circuit until peak inverse voltage (smallest diode) is applied on total resultant.Connecting diodes in parallel:Connecting diodes in parallel will increase the current carrying capacity of the diode.Connecting diodes in parallel will not get you a resultant diode conduction in both sides.
How does the positive clamper works in electronic circuits?
A negative clamper circuit is considered. It shifts original input signal in a downward direction.While positive input is applied, diode is forward biased. The output voltage is Vo which is equal barrier potential of the diode. The capacitor is charged to V-Vo.When negative input cycle, diode does not conduct because it is reverse biased and the capacitor can not discharge very much because time constant (RC) choosen is high. Now output is sum of input voltage and capacitor voltage and it is equal to -(2V - Vo). Now peak to peak output voltage is difference of output voltages when positive and negative half cycles and it is equal to V-(-(2V - Vo)) or 2V.In negative clamper, input signal is pushed downward and positive peak of the output signal coincides with zero level.In positive clamper circuit, unlike in negative clamper circuit, diode is connected reversely.There is no change in connection of capacitor. But resistor is connected after diode. Positive clamping circuit shifts a input signal in upward direction. The output of this circuit shows that negative peak of signal coincides with zero level.
What is the difference between a half wave rectifier and a negative clipper?
As far as general principles apply, they both perform the same function: using a diode.
How do you connect diodes in series?
Connect positive to negative, leaving the end positive and negative connections free to power circuits or devices. Connecting batteries in series adds the voltage of the batteries. For instance, connecting three 12v car batteries in series will create a total of 36v, enough for welding.

What is clipper in electronic devices and circuit?
clipper is an AC application of diode. The Clipper clipps off a portion of the input signal waveform without distorting the remaining part of the alternating waveform. We can use different type of alternating waveforms as input such as sinusoidal, Triangular, square etc. There are different types of clippers e.g. series clipper, parallel clipper etc. but the method for solving all the type of circuits are same. So there is no need to remember the procedure for one particular clipper circuit. There are different types of clippers e.g. series clipper, parallel clipper etc. but the method for solving all the type of circuits are same. Now let us discuss the procedure with the help of a problem. Suppose we have given a clipper circuit shown below: Because clipper is an AC application of diode. So we apply an AC signal at the input Vi. Our aim is to find out the waveform of Vo. The solution steps are: Step 1 : First of all analyze the circuit by bifurcating the input waveform in positive half cycle and negative half cycle.Step 1.1 : Positive half cycle : Positive half cycle is equivalent to a battery of positive polarity and variable potential.Step 1.2 : Negative half cycle : Negative half cycle is equivalent to a battery of negative polarity and variable potential. Step 2 : Now analyze the circuit with positive half cycle.The next step is to check the condition of diode i.e., whether the diode is forward bias or reverse bias.In the circuit shown above it is clear that the diode is forward bias and hence equivalent to short circuit (because it is ideal diode).Now analyze the variation of Vo.It is clear that And because Vi varies sinusoidally, so Vo also varies sinusoidally. Step 3 : Now analyze the circuit with negative half cycle The next step is to check the condition of diode i.e., whether the diode is forward bias or reverse bias.In the circuit shown above it is clear that the diode is reverse bias and hence equivalent to open circuit (because it is ideal diode).Now analyze the variation of Vo.It is clear that Step 4: Now combine these two waveform.
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.

How does a simple diode clamping circuit work?
A diode clamp, also often called simply a clamper, works by limiting electric current to a single direction and stops the signal from going beyond the reference. They can be either positive or negative, and biased or unbiased.
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.
Where is a diode used?
A diode is used as a rectifier, clipper and to get square wave form. The combination of diode (bridge) is used for full wave rectification. It also used as a voltage controlar. Different types of diodes have different uses in different appliences.
What happen to diode in parallel circuit connect into the series?
Diodes only allow the current to travel in one direction, they are often used to prevent current leakage from one point to another, "basically the current can back up and go into other parts of the circuit without the diode. If a Diode is placed in Series with a circuit it will only allow the current to flow in one direction. For instance in Power supplies that convert AC electricity to DC they use a special diode Called a bridge Rectifier, Basically it used 4 Diodes in series to smooth out and condition the power so that when it comes out it is only Positive and Negative Diodes are also Half wave, meaning that only half of an AC cycle will come out the result is an Oscillating DC. So when a Diode is in Parallel with a component it is either Bypassing that component in one direction or it is disallowing the current to flow Backward on the component..
Disadvantage of using diode as shunt element in clipper circuit?
In shunt clippers, when the diode is in off condition, transmission of input signal must take place to output. But in the case of high frequency input signals, diode capacitance affects the operation of circuit adversely and the signal gets attenuated (which means that, it passes through diode capacitance to ground).
What is the difference between a half wave rectifier and a negative clipper?
As far as general principles apply, they both perform the same function: using a diode.
