Quiz 2: Diodes and Applications

The anode of a diode is usually marked by a band, a tab, or some other feature.

Figure 1 -For the circuit in Figure 1, assume ideal diodes. The peak inverse voltage is approximately

Figure 1 -For the circuit in Figure 1, assume ideal diodes. The average voltage you should observe across RL is

To forward bias a diode, the n- region is connected to the positive side of a voltage source.

Figure 3 -For the circuit in Figure 3, assume practical diodes. The peak output voltage across the load is

Figure 2 -Refer to Figure 2. The circuit that will produce a negative output is

Figure 3 -For the circuit in Figure 3, assume a diode opens. As a result, the peak output voltage will be

An ideal diode is considered to have a small forward voltage drop across the junction.

When a diode is forward- biased, the depletion region narrows.

A silicon diode measures a very high value of resistance in one direction and very low resistance in the other. This indicates the diode is probably

The component(s)immediately preceding the voltage regulation stage in a power supply is

Figure 9 -The circuit in Figure 9 is a

Figure 4 -Refer to Figure 4. Assume the diode is a practical diode. The current in the diode will be

C:\User Figure 7 For questions 34, 35, and 36, assume ideal diodes -Which circuit in Figure 6 will produce the waveform in Figure 7(a)?

When a diode is reverse- biased, the current is normally extremely small.

Assume an ideal diode has a series 10 k▲ resistor and is forward- biased with a 20 V source. The current in the diode is

For a forward- biased diode, as temperature increases, forward current also increases.

Figure 5 -Refer to the circuit in Figure 5. The current in the load resistor is approximately

Dynamic resistance is the same as linear resistance.
