Answer:

Suppose you measure the resistance of an unmarked diode with an ohmmeter. When the (+) lead of the ohmmeter is connected to lead 1 of the diode and the (-) lead of the ohmmeter is connected to lead 2 of the diode, the reading is 400 Ω. When the ohmmeter leads are reversed, the reading is ∞. Which lead on the diode is the anode?
Answer:

Explain how you could use an ohmmeter to identify the cathode of an unmarked diode. Why is it necessary to know the actual polarity of the ohmmeter leads?
From the data in Table 5-2, compute the maximum power dissipated in the diode.

Does the diode's reverse resistance stay constant? Explain Your answer.
