Properties of Semiconductors: Practice Problem & Solution
One part of a device is connected with the negative terminal of a battery and another part is connected with the positive terminal of a battery. If their ends now altered, current does not flow in circuit, then the device will be: (1998)
Solution Explained:
To solve this problem, we apply the core principles of Properties of Semiconductors. Understanding the underlying formula is key to arriving at the correct answer below:
A P-N junction diode allows current to flow when forward-biased and blocks it when reverse-biased. Altering the battery terminals switches it from a forward to a reverse-biased state, matching this unidirectional behavior.
