Ask your students to reveal their information sources used when researching varistors, and also if they were able to determine how these devices are constructed. Question 3 Explain how a surge protector functions: Draw a schematic diagram clippers and clampers problems accompany your explanation.

Hide answer Some surge protectors use varistors, others use zener diodesand others use more advanced technologies. Question clippers and clampers problems A technician builds her own audio test set for use in troubleshooting audio electronic circuitry.

The test set is essentially a sensitive detector, allowing low-power audio signals to be heard: What purpose do the two diodes serve in this circuit?

Hide answer The diodes serve to protect the listener from very loud volumes, in the event of accidental connection to a large voltage source. Calculate this larger value, given a transformer turns ratio of My first encounter with this application of diodes came when I was quite young, soldering together a kit multimeter.

I was very confused why the meter movement had two diodes connected to it in clippers and clampers problems like this. All I knew about diodes at the time was that they acted as clippers and clampers problems valves for electricity.

Clipper and Clamper Circuits

I did not understand that they had a substantial forward voltage drop, which is the key to understanding how they work in applications such as this. Clippers and clampers problems this may seem to be a rather unorthodox use of diodes, it is actually rather common.

Incidentally, I highly recommend that students build such an audio test set for their own experimental purposes. Even with no amplifier, this instrument is amazingly sensitive. An old clippers and clampers problems over power transformer works even better when used in a step-down configurationgiving several thousand volts worth of isolation between primary and secondary windings.

The circuit even works to detect DC signals and AC signals with frequencies beyond the audio range. Your mileage may vary, depending on how good your hearing is, and how sensitive your headphones are.

As shown in the figure, the diode is kept in series with the load. This causes the positive half cycle to be clipped off. In Figure bthe diode clippers and clampers problems kept in parallel with the load.

This is the diagram of a positive shunt clipper circuit.

This causes the diode to conduct heavily. This causes the voltage drop across the diode or across the load resistance Clippers and clampers problems to be zero.

Thus output voltage clippers and clampers problems the positive half cycles is zero, as shown in the output waveform.

During the negative half cycles of the input signal voltage, the diode D is reverse biased and behaves as an open switch. In all the above discussions, the diode is considered to be the ideal one.

In a practical diode, the breakdown voltage will exist 0. Negative and Positive Clipping Waveforms 2. Biased Positive Clipper and Biased Negative Clipper A biased clipper comes in handy when a small portion of positive or negative half cycles of the signal voltage is to be removed.

When a clippers and clampers problems portion of the negative half cycle is to be removed, it is called a biased negative clipper.
