A zener diode has a relatively constant reverse voltage, at the designated zener voltage. If you had a circuit, say, with an AC source, a resistor, and a zener, the waveform across the zener would be the AC source, clipped at the reverse bias zener voltage, and clipped again at the forward bias voltage, typically about 0.7 V.

Can a magnet destroy an IC?
No a integrated circuit IC for short is solid state and can only be destroyed by reverse polarity or shortened output or to high input tension or current No a integrated circuit IC for short is solid state and can only be destroyed by reverse polarity or shortened output or to high input tension or current
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.
How must the two transistor junction be biased proper transistor amplifier operation?
A: Actually it is only one transistor required for amplification the other junction can be a diode. As current Begin to flow it causes a bias across one junction which is opposite biasing for the other, A good differential amplifier will have those junction virtually at the same point with a very good current source because any mismatched will cause and output without any input. It is called voltage offset on the other end if the feedback current is very small it will also produce an output voltage offset known as current offset or basically errors
How would you explain phase shift oscilater?
A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output.
How stability is achived in voltage divider biasing?
A: A transistor needs to be biased at a point whereby it is in a linear point with respect to the load otherwise it can give an output that is non linear or clipping. so with the proper bias the circuit is stable or useful.
What is encoder explain in brief?
An encoder is a digital circuit which accepts one of the inputs and converts it into BCD or Binary Coded Output. It performs the reverse function of that of a decoder.
Explain when step input is given to high pass RC circuit what will be output?
exponential
Why you use pushpull complementary symmetry for class B power amplifier?
Because the output device in a class B amplifier are biased at cutoff, they only amplify one half of the input waveform, so a complementary stage, biased at class B, is needed to output the other half. There are several circuit layouts to do this.

DC blocking in a transistor is achieved by?
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.

In which circuit will the light bulb be the brightest?
the circuit which has the maximum power output
What is output short circuit current?
The output short circuit current is the solar cell's current when the voltage is zero, or when it, is short circuited.
What is the function of capacitor in rectifier?
is a device that smoothen your half-wave rectification into a full-wave rectification after using a 4 diode and 1 resistor , after adding a capacitor , there will be a almost steady output , it charges the capacitor when is forward biased which is the first half wave , and discharge when is reverse biased to stablelize the wave into a almost same potential difference compare to a.c
