2.Electric current is not produced by solar cell when a. When holes move to the p side b. When both holes and electrons move c. When electrons move to the n side d. When both holes and electrons do not move

Most common materials for semiconductors are

4. Determine Vout for the figure below when the types of diodes (Si) and the resistance (R₂) equal 20.2. 1 V 2 V- 3 V + 2 ΚΩ www 2 ΚΩ + V out

4. Determine Vout for the figure below when the types of diodes (Si) and the resistance (R) equal 20.. + Vout www + 1 V 2 V 3 V 2 ΚΩ 2 ΚΩ

only left circuit please

Which statement is not true about an extrinsic semiconductor? They do not have equal numbers charge carriers. Their impurities do not affect their electrical behavior. They can be doped with another element by a process known as doping process. They are chemically not pure. Their electrical properties can be tuned.

The source voltage of the circuit is 5V and the break down voltage for the Zener diode is 5.2V then the voltage across resistor will be ??

In the circuit shown in Figure 2–41 (p. 94), the current I is 34.28 mA. What is the voltage drop across the diode? What is its dc resistance?

Sketch the i versus v curve for the following (the voltages beside Zener diodes represents their Zener voltages): i (a) (b) X 2 + 2 Ć V₂=5.6V S.6V 5-6v

The primary voltage on the transformer in Figure 2–46 (p. 96) is 120 V rms and NP : NS = 15:1. Diode voltage drops are 0.7 V. (a) What should be the value of RL if the average current in RL must be 0.5 A? (d) Is it alright to measure with an oscilloscope both the input and output waveforms at the same time in Figure 2-46?  Why or why not?
