How does a diode clips the wave when it is forward biased in clipper circuits?
A diode only allows current to flow in one direction. When the voltage exceeds 0.6 volts it will not allow more voltage to flow. Putting two diodes cathode to anode would limit the voltage both ways.
Can you use resistance in place of diode in clipping circuits?
no we not use resistance in place of diode.

How diode acts as clipper and clamber?
A diode acts as a clipper by preventing a portion of the input signal from passing through, effectively "clipping" the waveform at a certain voltage level. This is achieved by connecting the diode in such a way that it conducts only when the input voltage exceeds a specific threshold, allowing only the desired portion of the signal to pass. Conversely, a diode acts as a clamper by shifting the entire waveform up or down without altering its shape, typically by adding a DC offset. In this configuration, the diode allows for the movement of the signal to a new reference level while maintaining the original signal's amplitude and frequency characteristics.

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.
