Answer:
To test a diode using an ohmmeter, we need to understand its behavior in both forward bias and reverse bias conditions. A good diode should exhibit specific resistance values in each bias condition, allowing us to identify its functionality.
Forward Bias:
In forward bias, the positive terminal of the ohmmeter is connected to the anode (P-type material) of the diode, and the negative terminal is connected to the cathode (N-type material). This creates a forward voltage across the diode.
A good diode should have a low resistance when forward biased. This is because the forward voltage allows current to flow easily through the diode. The low resistance indicates that the diode is conducting properly and allowing current to pass from the anode to the cathode.
Reverse Bias:
In reverse bias, the positive terminal of the ohmmeter is connected to the cathode, and the negative terminal is connected to the anode. This creates a reverse voltage across the diode.
A good diode should have a high resistance when reverse biased. This is because the reverse voltage blocks the flow of current through the diode. The high resistance indicates that the diode is functioning correctly in its blocking mode, preventing the flow of current from the cathode to the anode.
Summary:
Based on the above explanations, the correct answer is option 'C': A good diode should exhibit high resistance when reverse biased and low resistance when forward biased. This behavior confirms that the diode is functioning properly and allows us to identify its characteristics using an ohmmeter.
